We just got off the boat. Worst cruise ship experience I have ever had. I traveled from Greece to Rome and from Rome to Civitavecchia. I took a shower and the cold water didn't work. Literally a hot bath with 30 degrees Celsius outside.Not only that but the bath overflowed. They repaired it at midnight. Also, I paid for a cabin with a balcony and I didn't even see the sky, because above my ...

After approximately 30 hours of Costa I asked my husband to check on the money back policy I would have done so earlier but we had our daughter and his mother with us and we had no alternative plans. This was by far the worst cruising experience we have ever had. Everything about it is bad. It's noisy everywhere all the time, there is no relief. The staff is rude. I've never seen rude staff ...

Bad. Horrible. Worse. Discrimination towards English speakers. Inefficiency.

I want to preface this review by saying I'm not often a big complainer. I can roll with most annoyances with ease and I rarely feel the need to make an issue. But this was by far the WORST CRUISE in my entire life. Why did we go? Never been to Europe before and Costa had numerous itineraries, dates, and prices to choose from so it was the sheer availability of options that other lines simply ...

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 ...

restaurants was of poor quality and service was poor. The crew were rude and not very helpful. You ask a question and the crew person would turn away and walk away. We were 12 people from the USA and all 12 of us felt like costa did not want our business. The crew just made you feel unwelcome The room did not have towels or wash cloth After a meal if you want coffee or another ...

This has been my absolute worst trip ever (I have travelled to over 60 countries) and never experienced such a lousy service and environment in all my previous trips! -Paid over 1500 Euro for a inside cabin per person with unlimited drinks for this trip for me and my girlfriend. -I was lied to about price of drink from bartender and later, I AM NOT trusted by the receptionist. (Johnie Walker ...

Wanted a exclusive dining experience for Christmas. Got Hell Costa Diadema Christmas in the 'Med' 18th Dec to 31st Dec 17 B2B. The term 'never again' comes to mind unfortunately we have already booked this ship again for five weeks' time. Making allowances that it was the lead up to Christmas we expected a full ship & lots of children, fair enough we have been with Costa lots over ...

We wanted to try to cruise with Costa. The embarkation was not organized. People lined up wanted to get to the ship as soon as possible, despite we got our number to got in. The room was cline. Lunch for the first day was fine, but no coffee or tea, had to wait till 16.00 pm,unless if we pay for it. Dinner was not good, soup was not hot, very hectic. The waiter was unpatient to take the ...

I wanted to take my mom on a cruise for her upcoming 65th birthday as she loves cruises and they're usually the best way to relax and visit so many different countries/places. We have cruised before with Norwegian Cruise Line and I have cruised myself several times with Carnival, but as she lives in Bosnia and Herzegovina now, so the closest and the best cruise that worked for the dates I was ...

Horrible experience with Costa Diadema

First Time Cruiser • Age 20s

The story with Costa started badly from the beginning. It was our first cruise. When we were getting on the cruise, we were attended by a person who barked at us in an incomprehensible language and forbade us to enter because of a non-existent schedule problem. Behind him came an officer on board who, in very bad manners, let us reluctantly pass by the cruiser. On entering, we asked for the ...
