This was our eleventh cruise. The ship is huge and beautiful, and the performers/entertainment is clearly the best we have ever been exposed to, with the capability of doing Circue De Soleil-esque difficult performances, Broadway, and 70's rock performances. The Cruise director, Patti, must have made outstanding selections.
As customary for Celebrity, the food is aft and the theater/gym in front. You have to walk at least 300 yards to get from one to the other.
We had chosen a cabin on the forward port side on Deck 8. On the first night, after the ship left Settle and was moving around 18 kts in the open sea, Our cabin experienced creaks and groan sand kept us from getting a good night's sleep. The next day, I complained to the Customer Relations staff, and they apologetically gave us a different room midship.
I have never experienced this on my 10 previous cruises, but the crew tell me that it occurs somewhere on every ship.
