My 8th cruise (Royal Caribbean- LOS, VOS, Cunard, Princess) and first on Celebrity. I chose this ship over the sister line Voyager of the Seas as it had a marginally better itinerary. A mistake!
We were in Concierge class with a balcony and an inside stateroom just down the corridor.
First the good things:
Concierge class. Aft. Starboard. Very roomy and lots of storage. Well organised bathroom. Table a little small for breakfast. Large enough balcony for lying back in deckchair. Noisy neighbours very clearly heard. Everytime they opened or closed their stateroom door, it sounded like our door was being opened (rather alarming initially).
