We chose Celebrity Reflection because it fit into our time frame and went to many sites that we wanted to see. The ship is very new and it great condition. The service was excellent. We were hesitant to pay the extra money for concierge level but were glad we did. Our concierge, Aldin, made sure we had everything we needed and even arranged for a special dinner for us. Some other things you get with concierge level are a bottle of champagne, hors d'oeuvres every afternoon, free shoe shines, and special help with anything you need.
We were also invited to stand on the helicopter pad to enjoy our sail away from Barcelona.
Before our cruise, I read some negative reviews about the entertainment. I'm not sure what those people were watching but I thought the entertainment was excellent. Our favorites were Jon Courtenay who did a comedy/piano show, Raegar (who did a rock & Roll/country show), and the aerialist show. But all of the shows with the Reflection singers and dancers were great too.
Our cabin seemed smaller than what we have experienced on other ships. The couch took up a good deal of the room. It would be nice if you could choose a room without a couch/bed if there are only two of you. I will say our cabin was kept impeccably clean by our cabin steward Sheryll and she even decorated our bed with a swan and rose petals on our anniversary. I would recommend getting a cabin one floor lower, though, because we could sometimes hear noise in the cafeteria above us.
