We chose Celebrity because we had read good reviews online. We initially wanted to book a smaller ship, but wanting a larger suite for this cruise, Celebrity was more affordable.
The ship was lovely, the staff and service excellent. The food was very good almost everywhere on the ship, although the Lawn Grill was terrible. It would have been nice to have a place similar to a sports bar or pub where we could have had a really casual dinner, like nachos, tacos, or burgers. (And, I am not talking the pool grill or the buffet)
Our room was very comfortable, but I would specificially NOT recommend our suite... Suite 2188, as there was a loud, mysterious noise from somewhere that woke us up over and over at night. It sounded like someone was dropping wire hangers into a big metal pot.
DO NOT BOOK THIS ROOM! NOISE WILL WAKE YOU UP ALL NIGHT LONG
