Celebrity seeks to treat its guests "famously" but this cruise didn't quite live up to that. In fact, if you put me in a blind comparison to my Royal Caribbean cruise, I'd have said RC was the premium line, and Celebrity the mass market. (Have also cruised with Princess, Norwegian, Holland America). Overall, while the staff were very friendly, the overall ambience just wasn't what I'd expect from a "premium" line.
We had a concierge class balcony stateroom, and the stateroom was comfortable - particularly appreciated the full size shower. Unfortunately, the balcony was very small and had no lounge chair, only upright chairs. No towel animals and the linens were not renewed as frequently as we'd like. Room service was good with a wide menu. Ability to order through interactive TV was handy.
Lowest marks probably went to the food - variety and quality not that good in the main dining room, and service was fairly slow. The buffet had more options, but pretty much the same options every day - no themes or rotation, as on Princess. Appreciated the always-available lemonade and punch, and ice cream - some of the few upscale touches.
