This ship was chosen by a friend,we were a group of 8, because of price,doing research after cruise ended this became evident.We are from U.S.A.and have cruised Carnival to Alaska,Celebrity 2 years ago to Mediterranean and others and this ship was the least enjoyable.This line is owned by Carnival along with many others so when we saw that even water at lunch was extra unless you had a USA on your the back of your card. The standard formal night even charged $25 extra for lobster. The cabins were pretty standard,we had booked a balcony but the smell of cigarette smoke and overflowing toilets were in hallways or in room was an issue.Unlike other ships we traveled on this one picked up passengers at several stops during our 7 days on board so instead of resting in your room your got the alarms and intercom blasting for muster drills. The ship carried people from multiple countries so things were repeated in each language,and this continued on excursions the tour guides spoke in at least 2 languages.One tour was English and Spanish but the accent was enough that I had trouble understanding the english.

Our friend selected this cruise for his first cruise and first trip to Europe. We are faithful Celebrity cruisers so I use that cruise line as my baseline. The price of this cruise included the cruise cost, airfare, and hotels on arrival day and day of disembarkation. The Diadema is a fairly new ship that accommodates about 5000 people. People are able to embark and disembark at any of the ports, I believe. For Europeans with families this probably makes it a fairly cost effective cruise. That being said, there were way more people on this ship than on Celebrity. And there were way too many kids. The atmosphere just seemed chaotic. Kids on the dance floor at 11 pm is not my idea of a good time, for example. There are no adult only activities on this ship. The ship is very nice and clean. Cabins are only cleaned once a day. The food was mediocre at best and the choices at the buffet were rather limited compared to other ships. The staff did their jobs competently, but were not the friendliest. We are used to the “welcome back” and smiles that the Celebrity crew provides at all times. Our waiter in the dining room was great, however. A bit of advice if you are booking on the Diadema: beware of the 9th deck. The buffet and pool are over some of the cabins and the noise from these areas is unbearable at times. Chairs were scraping the deck above at all hours. Better to book on a lower deck unless you enjoy being awake half the night. The thing that I liked the best about the cruise was the itinerary. I’ll be sticking to American cruise lines and smaller ships in the future. Read Less

Booked this western Mediterranean cruise to visit most ports that I had not been to. I also had never been on Costa or any other Italian flag ship. I had cruised Carnival, Norwegian, Royal Caribbean, and Princess on a total of 8 cruises. The advertised cost seemed reasonable, but then came added things, like water package, drink package, and specialty restaurants like the ice cream bar and the Pizza restaurant. Other high end restaurants are also available. The pizza at the pizza restaurant was the best food that I had on the ship. The Pia Gusto drink package was a reasonable buy which covers most drinks and coffees. The Illy coffee is probably the only thing that would get me on Costa again. Dining room food was the poorest I have ever had on a cruise line. Our waiter seemed burned out, but maybe he was near the end of his contract time.The fact that they board and disembark passengers at each port means less waiting at disembarkation, but annoying safety drill announcements in six languages at every port. The pay for pizza was nice because the pizza was excellent, reasonably priced and because it cost a little extra there was no waiting, which I’ve seen on other ships with passengers that can eat them as fast as they are produced. A small cost for exceptional coffee is much better than other cruise lines “swill coffee”. The passengers are probably 80% European, which means limited chatting with your fellow cruisers which to me is a disadvantage, interacting with fellow cruisers is usually part of the fun of cruising. Would I do Costa again? Probably not. Read Less

I chose this cruise because of the ports being visited and the low cost. The internet service was horrible, and when I complained and asked for a refund, I was told that it wouldn't be possible. They canceled two of our pre-booked shore excursions - one because it was on disembarkation day (hello - why was it even offered, and why did they let us book it?), and the other because there were not enough English speaking passengers. The next day; however, we were on a shore excursion with 47 English speaking passengers and 4 German passengers, so we had to listen to the whole thing in both languages. Why couldn't they have done that for us on the previous day? The entire cruise catered to the Italians, and it was tiresome to have to hear everything in 6 languages, not to mention that it was clear that they were joking and laughing with the Italian passengers and not translating what was happening to everyone else. They were very chintzy when it came to game prizes (one prize for the whole team, and it was always a thin little tote bag), and the only activities were one or two video quizzes and dance lessons. Bingo was expensive, only played twice, and only one game each time. The food was awful - obviously frozen and thawed, not cooked fresh, and the same old items every day in the buffet, and only 3 choices in the dining room. Water, anywhere but the dining room or buffet, was not free, and in the dining room it was only free for the Americans. Staff was often rude for the most part and didn't offer any accommodation for any complaints or problems. Because every port was an embarkation/debarkation port, the elevators near our room were closed down all afternoon, and then we had to listen to the muster drill more than once. Your credit card is billed in daily increments that never match the daily charges, though the total did appear to be correct. Read Less

The Ship was amazing, we were well impressed with the Shows, the food was lovely and a good choice but it was never more than lukewarm which was a shame, the staff work so hard and are so friendly. We bought one of the middle drinks packages it and proved to be a godsend as the drinks were expensive. We did find it hard work getting back on the Ship after a trip. I also slipped up on deck 10 near the Lido Buffet and had to see the hospital doctor who's bill was €352.00 of which €100 was for a BANDAGE which is a bit extreme by any standards, really thought I would at least be able to use my EHIC as it was an accident onboard , this then spoilt my holiday as I had badly damaged my knee so was in a wheelchair for the 4 days out of 7 and unable to take the wheelchair on shore.

We were offered a package with airfare and cruise. Seemed like a good deal. We had previously discussed visiting some of the cities on the itinerary, First glimpse of Costa infrastructure technology was when we tried to log in to the MyCosta website It asks for your first name, surname and your "BOOKING REFERENCE" Login always fails unless you omit the first name.. We asked for where it boards. "Barcelona" Which dock ( there are 3 or 4) crickets.. Got on board, and went to check on our pre-reserved packages for beverages, excursions, etc. Most could not be found by the staff. I went outside, where I could get internet on my phone. Logged in to the MyCosta website, and saw that all my bookings were still there. Never did completely sort this out, so every time we ordered a drink the staff would have to double check for our drinks packages as they did not show in our ship cards. First night we went to dinner. We had booked for the "Main dinner from 21 O'Clock" They had us down at "Early Dinner form 17 O'Clock We had booked the Fiorentino restaurant on Deck 3 They had us in the Adularia restaurant We did not care much which restaurant, but did not want to eat at 7. They changed this for us. Second day was to be at sea, and I had booked for my wife to have a Swedish massage - 50 minutes, in the spa. Cost of 99 Euros Of course they "lost" the booking. I checked on My Costa the next day in port, and it was still there. This did not help me that day, so I had the spa rebook it. My wife was booked at 4 p.m., so she went and had the massage. They gave her the "Elemis Asian hot stone massage - 50 minutes" and charged us 154 Euros. They told my wife at the end of the massage that her skin looked quite dry, and sold her a package of 3 different skin lotions to help that. She signed the slip, and did not look closely. When she got back to our cabin she mentioned, so I asked for the slip. They had charged us 595 Euros for the lotions! We went back to the spa and wanted to return these ( unused and unopened, same day, within an hour) They tried to refused. I asked for a manager, and was told that she was not available. I complained to the cruise service desk and asked to speak with a manager. They spoke with me and an appointment with the spa manager was booked for 7 p.m. the next day. We met, she acted all surprised, and accepted our request for a refund. She accepted that, but that the refund had to be done in 2 days later, at Savona, at 10 am. The next day ( and a day before the credit was supposed to happen) they processed the charges against my card for $1,015 CAD The next day ( as arranged) and time I went back to the spa, and ( of course) the manager was not available, and the staff could not do anything. Went back to the cruise ship service, asked for a manager again, and was asked to wait for 20 minutes. Apparently some decision was made in the background, as, when I returned 20 minutes later they offered us the credit, which we accepted, and was processed on the last day of our cruise.. On that day I told them that unless I could log in to my card website and see the credit there I was not going to leave the ship. Drink packages: We booked 2 drink packages: "WATER, COFFEE & BEER PACKAGE" for 69 Euros, to include: " package of 7 water bottles (1lt), 7 draft beers (40cl) and 14 coffees (normal or decaf)." This actually meant: 7 water bottles, 7 Heinecken drafts, and 14 espressos. If one ordered a coffee with milk, they made us cafe latte, and charged our card for 3 Euros. We finally learned that if we ordered an "Americano with milk" we could get this, actually made identical to a cafe latte, and put it against our prepaid coffees. They would not credit us for the 5 previous coffees we had, at a cost of 15 Euros. Cabins: We selected an inside cabin, midships. It was clean, comfortable, and very quiet. Only complaints: TV remote did not work ( they replaced) Only 1 AC power outlet in the whole suite. Bar fridge did not refrigerate. In general, the staff service was quite good. The sit down meals were Italian food and very good with excellent service The buffet meals were chaotic. Running out of many items very fast. They acted like they were preparing to feed 500 people and 1500 had shown up. They charge an automatic 15% gratuity on all purchases, food and beverages. This is not included with the prepaid drink packages, and is charged extra. They charge an extra 10 Euros per day, per person, service charge. Basically the practice is to "nickle and dime" one to death on everything. Most of the ports were as expected. One, Savona, in northern italy is a former industrial town with a population of 61,000. As Wikipaedia describes it: "Savona used to be one of the chief seats of the Italian iron industry, having iron-works and foundries, shipbuilding, railway workshops, engineering shops, and a brass foundry." There is little to see or do there, and apparently it is chosen as it is fairly close to both Genoa ( 56km) away and Monaco ( 132 km away. Pardon my saying and apologies to the citizens of Savona, but it is a bit of a :"shithole" In either case an excursion is a trip by bus for about half the days travelling by roads. I think that Genoa would have been a much better destination, See: https://www.cruisecritic.com/ports/newport.cfm?ID=181 I just looked on Google Maps and saw 2 Costa ships tied there as of the day they took the satellite pictures. In summary: Nice ship, good food, cheap and disorganized cruise company. Will not be back on their ships. Read Less

- I got a last minute offer from an agency (on 2nd January and the cruise started on 5th January from Savona), and it was a good value for the money paid, but if I had to pay the full price, I would be disappointed. It was not our first time cruise with Costa, but in general the service is of lower quality than on MSC and that reflects also on prices. The embarkation went smoothly when our time arrived, but we had to wait for more than 1,30 hrs although we arrived late (approx. at 15,00 h). Usually, when we arrive this late we are immediately scheduled for embarkation. The disembarkation went more smooth, since we waited until 10,30 h to disembark, and not push to be the first to get off the boat. SHIP - the biggest in the Costa fleet - a small city on the sea - balcony cabin on the left side of the boat (8th deck); great, spatious cabin, always clean; got a bottle of sparkling wine since I am in the Costa Club - the cabin choice was good for some rough sea that we have experienced - Dining restaurant is huge, service staff was nice, but it took them a long time to get us drinks; also, since I bought a package of soft-drinks, once they get us drinks in glasses, and once we got them in cans (more hygenic) and the size is different. Food in general is of average quality, but it downgraded from our last trip (in 2017). There is no more scrambled eggs, the line for breakfast eggs is soo looong, there are no American pancakes for breakfast. The staff in Diana Restaurant (deck 10) is generally less hospitable than in other restaurants. The ship was overcrowded with families, well, basically with kids, but we are used to this. If you are looking for a high-class cruise, peaceful and with lots of attention, this is not a cruise for you. Entertainment was great, and we loved Jose Navarro, the tenor. Service in our room was good, although we were a bit surprised that we did not received 3 hand towels but only 2 although there were 3 adult persons onboard in our cabin. Service in general area and in the restaurant Adularia was good. Ports visited were great, but we have visited them already, and we enjoyed visiting them again. The tours booked on the ship are too expensive in general, so we opted for self-organised tours, mostly with taxi (cheaper, visited some other places, had enough time to visit inside the building if we wanted, get time also for shopping and return to the ship afterwards - like with our private driver and guide). I travel with my teenager doughter and she was much happier 2 yrs before, because we had more international group. Italian kids do keep for themselves and do not mix much with others. We will definitively go for another cruise, but maybe with a different fleet, different ship or different itinerery. Read Less

Briefly; SAMSARA SUITE #11005 - the second largest cabin size on the ship (I believe) - ONE plug socket for guest use (oh and one behind the wall mounted TV) - Massive balcony with tub but horrible blue fluorescent lighting (stops junkies I guess) - Poorly designed bath screen needed a dressing robe cord to stop it banging all night - WiFi signal practically non-existent - Very noisy cabin stewards outside door from 7am - Very noisy "vacuum flushing" system every 10-15 mins from 7am (not toilet) INTENDITORE Drinks Package - massive choice of two wines available at bars (majority of which are closed until 7pm/8pm) - Heineken the only draft beer available (or their own draft from one bar open from 7pm) - No cordials such as lime, blackcurrant etc (maybe too expensive at 30p a litre wholesale) SERVICE LEVELS - bar/lounge service ranged from OK to extremely slow - I go out of my way to be polite to staff but it made little difference on this cruise BUFFET RESTAURANT - went once - not to be repeated - cold food, limited choice and no method in its layout (treasure hunt to make a meal) THE CLUB RESTAURANT - staff training = zero - maitre'd was their for his benefit not to ensure the guests had a great experience - rushed courses despite asking several times for it to be slowed down - plates removed while my wife was still eating - new cutlery put in place even while my wife was still eating - extremely (EXTREMELY) limited choice but what we did have was nice - please, no more mozzarella or pasta dishes (Italians cannot eat only this surely) - vegetables twice in 7 days (5 runner beans one day and a carrot on another) - screaming children running around restaurant (its supposed to be a dining experience) SHOWS / Venues - Italian and in Italian (90% of the time) - but I expected it so was ready I guess - very little variety of music around the bars and minimal seating in most - theatre layout really poor - estimate 20% of audience could actually see the whole stage ENTERTAINMENT (quizzes etc) - italian and in italian BILLING - overcharged 114E so queried at reception only to be told I had to go to the Spa to get it corrected. I had never set foot in there so why do they expect their guest to do all the chasing - overcharged again by the Spa - this time for 210E. I went there this time as I was closer to them than reception. The Manager simply told me "you really shouldn't worry about these things, they will get sorted" - perhaps if they didnt happen TWICE for somewhere I had never set foot in, I would have been a little more understanding. DEPARTURE - carry your own luggage as this helps you to get off the ship faster (you will thank me) SUMMARY We have now taken 41 cruises, 6 of which were on another Italian line MSC. Costa is by far the WORST cruising experience we have EVER had. The noisy, rude groups of Italians weren't the issue as they're on MSC too. Just about everything about Costa was the problem - poorly designed ship - minimal staff training and therefore mostly poor service - limited bar times and extremely bad choice of drinks in each - poor but expensive wifi - limited food choices in The Club Restaurant - billing issues TWICE Yes, Costa are a cheaper alternative - but they don't even seem to want their guests there.

This was our 3rd with Costa (and 26th overall) and we had always had great experiences previously with Costa so did not expect anything different on this cruise. We were very disappointed overall. The ship overall was very nice. It was well maintained and decorated nicely for Christmas. Whilst the layout of the ship is not the greatest (you have to go up or down to get where you want to go sometimes) and the public toilets are not well signed, it is functional. Getting on/off the ship in ports was possibly the easiest ever. Debark we were off the ship collected our luggage and on the bus within 5 min of our appointed time. Now for a quick review on each area - Cabin - Despite many complaints it never got below ~22/23c - the only person who cared was our cabin steward. Food - MDR - Very inconsistent in quality/taste/variety/service. The first night dinner took just under 3 hours and on average we were 2+ hours with the first dish coming to the table approx 1hr after sitting down. One night I ordered from the kids menu to find something I would be happy with (I am a picky eater, but can normally find something I can eat). Also Breakfast was always a Scrum, even though I thought they did a great Ham and Cheese Omelette, I could not handle the craziness. Buffet - Very inconsistent in quality/taste/variety/opening. It was a treasure hunt to put an actual meal together. Teppanyaki - By far the worst we have ever been to. It was tasteless with some poor quality meats and the show was not good either. Burger Place - Decent but nothing to write home about. PIzza Place - Yes you have to pay for the Pizza - This was by far our best meal on board. Staff - Except for 3/4 people I found most staff to be rude/unfriendly. Now I don't expect a lot but common courtesy goes a long way. Bars - Overall quite limited. We ended up in the Beer bar on deck 5. Even at €2.50 a beer with our package was worth it. Also the service was top notch! We did speak to the Hospitality Desk about some of our concerns and the International host called me back 2 days later to discuss them. Offered Pizza or Crepes as an apology, I suggested an OBC to cover part of the teppanyaki and she said she would see what they could do. Here I am at home and I am still waiting to hear. I want to be very clear, I was not expecting any credit when I complained, I really just wanted a colder room. I did however think the Panettone left in the cabin on Christmas Eve was a nice touch. I could continue, but overall we are just disappointed after great experiences previously. Read Less

We already took a Costa cruise in the Adriatic sea and enjoyed it. So we decided to go on another Costa verses switching to another cruise line. We joined the Costa Club and had some perks for going again. We booked directly with Costa but used the Italian booking site. We received so many perks and extras for booking via the Italian site. We had a Balcony Premium for 2 adults and 2 children.(8 and 12) it was a great amount of space. We weren't ontop of each other during the week etc. We brought our own 220V extension cord so we could plug in all our devices. The food was great. This boat had an option of "Open Seating" for one of the evening meals. Same menu as the "Fancy" service dinner, but quicker (it seemed) and I felt better for our family. The service crew was amazing. My husband was practically a celebrity at the end of the cruise with many of them knowing his name and saying "Hi" around the boat. The crew was also helpful and wonderful to our children. The kids club had more international kids on our last cruise, this one had many Italian so my kids didn't do the club much, but it was a good size club space and activity schedule was great. It would be great for younger children. We are use to the multi language environment, so the multiple language didn't bother us, we enjoyed it. Read Less
