This was my first time sailing with Celebrity. I had a really good time and the onboard staff were great. Cruise Critic was very informative before I left (a lot more helpful than the FAQ and pre cruise online customer service for celebrity) so I want to answer some of the questions people had before they sailed.
We had a kettle in our room. Also had a handheld hair dryer in addition to the wall one in the bathroom. Robes but no slippers. Masses of shampoos etc, extra hangers upon request, wine glasses in room.
We had anytime seating and could always show up (6 of us) and get a table right away in the dining room without a time reservation.
