My husband and I cruise extensively and we loved this ship! We've been on RCL, NCL, Disney, Princess, Holland - Celebrity is always our favorite - and, this holds true for the century. It's size was just right for us, as we were traveling without our teenagers this time (no need for Flowrider, etc).
The ship has a very nautical feel, a lot of wood and intimate spaces. The service throughout the cruise EXCEEDED all of our expectations - the room stewards were incredible, the MDR service was amazing, and the bar staff throughout the ship was very attentive and pleasant.
Food was good (we aren't real picky eaters though). We did go to Murano, a little pricey at $45 per head - but a great experience. (Tip: I had the lobster, if I had to do it over, I'd have had the Chateaubreiand, wasn't crazy about the Dijon sauce they out on the lobster and the steak smelled incredible!)
Great room location and a little different shaped - pretty roomy for inside stateroom
