Don't be swayed by negative reviews, we've sailed with P&O, Fred Olsen etc and were a little dubious about this ship but decided to go with it as the itinerary for the caribbean suited us perfectly plus we prefer the smaller ships. Admittedly on embarking the Celebration first impression weren't brilliant but all I can say is the ship's ambience and charm grows on you not to mention the crew.....
Our spacious cabin on deck 1 was great - large double bed, double wardrobes (30 rigid hangers), tea/coffee facilities, hairdryer, more drawers than we could fill, flat screen tv with SKY sports/news , the usual small but manageable bathroom and the most wonderful cabin steward (Aris).
The entire ship is kept absolutely spotless by the attentive crew including the outside deck areas which were cleaned overnight. The food was absolutely fine with several dining options, We loved the Meridian restaurant, open dining meant that we chose to sit with fellow passengers, meeting different people each evening - speed dating at sea!!. Drinks and wine packages available were very reasonably priced (if not on the all inclusive option) and we loved the coffee pot for our daily Lavazza fix with cake.
