I've cruised with many different lines, over the years. This was my first time with Celebrity, however, and I was excited after "hearing about" (IE- seeing on tv) it's acclaim.
All I can say now is...just don't go. Here, let me break this down for you future-cruisers:
1. FOOD: was acceptable, but not in any way up to the standards of Holland America or Royal Caribbean lines. Only two main dining room dishes were memorably good: a honey-pear chilled soup, and the creme brulee. The "specialty dining" (ones that you pay extra for) actually outnumbered the regular dining options; while the extra fees were reasonable, I myself didn't choose to dine in one of these fancier onboard restaurants. I heard mixed reviews about them, particularly QSine- people either loved it or absolutely hated it.
Stateroom was adequate, if a little cramped; they usually are! Our stateroom attendant was impressively cheerful, fast, and ninja-like. She always stopped to say hello and have a chat, though! She was the only staff member I felt was deserving of a tip (although we tipped pretty much everyone). The bathroom in the cabin was a bit smaller than usual, I feel, but was still manageable. Unfortunately, due to utter lack of entertainment on board the ship, I spent a fair amount of time in my cabin!
