We had a very good time cruising with Celebrity. It was our first time after two trips on Carnival. We met lots of very friendly people. Our staff on the ship did an excellent job! We have been pleased with this aspect on both Celebrity and with Carnival. Much fewer children on Celebrity which made it quieter and more enjoyable. You could actually use the pools and hot tubs. On Celebrity, there were no children running down the halls on the ship at night unsupervised.
Our Celebrity ocean view room was nice, but not as nice or as large as our Carnival ocean view room. Also the bathroom was much smaller on Celebrity. It was difficult using the closets on Celebrity when someone was using the bathroom. The doors lined up so if you were using either at the same time, there would be a collision. We've heard the newer Celebrity ships have larger staterooms and are quite nice.
The entertainment was much better on Celebrity. Acts seemed more professionally arranged and performed.
