We sailed Celebrity a few years ago via an MGM Resorts deal, I spent a lot of time in the casino which was very modern, was also surprised to be offered random gifts in the casino, I opted to take a branded bottle of perfume. The gift was very unexpected but nice.
The ship is awesome. Everything was perfect except for one thing there is no casino bar when you want to drink in the casino you have to hunt somebody down. If you don’t drink this is the best ship out there. I probably will not go on an edge ship until they put the Casino bar in there.
