We have cruised other cruise lines but heard that Celebrity was top notch. We booked Concierge Class on this ship and were assured a butler and preferential treatment.( It was our 20th anniversary). From the moment we boarded it went down hill. Our room was filthy. We had to request it be cleaned twice! No butler service or preferential seating promised. We could not get traditional dining as we were told it was full. However, each night over 100 seats were empty and available. Configuration of the cabin was such that the bed was in the middle and had to almost crawl over bed to get to the couch, balcony, make-up desk with mirror, The food was honestly so poor that two nights we went upstairs to the buffet and had pizza. One could not use the sauna or steam room without paying each time even when one took a class or used the gym. We could not even get a light fixed...and add insult to injury they painted our balcony the morning of our last day! We were never asked or told..we were just greeted with a sign "Wet Paint" . Due to this we had no use of our balcony our last day/evening. The shows were not very good. If you think I am a cranky complainer the others we met on the ship had worse experiences! Each encounter with other passengers were worse and worse. One person could not get seated for dinner new Years Eve and was told "there was no room. Sorry" Another couple told us their room had to be scrubbed for 1 hour due to the filthy condition. Another told us about their door coming off it's hinges on her! It just goes on and on. Sadly, any screw up was greeted by chocolate strawberries to the point I just left the 5th dish of them outside the door. There were certainly ways to make things better. After 1 day, the strawberry plate got old. The employees seem trained in "no" and "can't" on ANY issue even the smallest. The captain was busy being a comedian, playing volleyball and game show host. This detail may seem trivial but I would prefer my captain to head the ship and it was operating poorly. Constellation is an old ship. There were many things that could be done to improve the food and service. This is not going to happen. Please pick another cruise line or at least new ship!
