We chose a concierge class cabin so we could have a specific cabin (which had an extended balcony at the rear of the ship). The cabin was a typical size: small bath with shower, plenty of closet and drawer space, a comfortable sitting area and a very large balcony, which we used just a few times. This cruise had only 2 seas days, and we spent those up on the pool deck, leaving very little time to spend on our own balcony. We were a bit disappointed with the service from the cabin attendants; we had expected great things with our "Concierge Class" designation as described at the Celebrity Cruise web site. While a bottle of champagne and fruit were awaiting us when we arrived the ice had melted and the bottle was no longer chilled (it took us two days to get them to refill the ice bucket) the three apples on a tray were a let down as well.
We dinned in the main dining room and the food was good to very good and the service excellent. The food at the buffet on the pool deck we found to be fair but convenient. The entertainment was typical cruiseship quality, good but nothing spectacular.
The ports we enjoyed the most were St Marteen (great shopping) and Antiguia (post card picturesque).
