We chose Aqua Class for the first time and it is well worth the small difference in price from Concierge Class. The restaurant experience alone was worth every penny and helped make the cruise a great experience. Blu offered a wide choice of dinners and I am happy to say I never had to resort to the "Classic" menu offered every night. The staff in Blu were accommodating and got to know us very well, always a plus. Our excursions were well organized and offered a nice easy trip to the Butterfly Conservatory in Key West; a glimpse into the Mayan Culture at Costa Maya with comfortable transportation and knowledgeable guide; a fabulous submarine experience in Cozumel going 112 feet down to see the reefs, fish and scuba divers; and a not so great ride through Grand Cayman that Celebrity reconciled quickly and easily as many of us were not satisfied. In a word, Hell wasn't worth the trip and since we live in Florida, a trip to the beach so late in the day was a bad idea. The entertainment was terrific as the on board troupe of performers were very talented and came up with interesting shows. Other on board entertainment, such as the guitar player, make for great bar experiences listening to him play. The cabin was clean and big enough and we were lucky to be on a slant so our balcony was a little bigger than we were used to. Overall, I think we are sold on Aqua Class and are looking forward to our next cruise which we booked on board this one.
