It was a wonderful cruise on the Oasis of the Seas. The staff in the Casino is by far the best of any ship or cruise line. I was invited to a sail away party for casino guest. Free drinks and horderves. Sergio one of the Casino Host from Argentina was very exceptional as well as the other two host. Wonderful to see the casino is divided for smokers and non smokers. My clothes didn't smell the next morning. LOL Only issue I have with Royal Casino is the "machine dealt" Ultimate Table. It broke early on in the cruise and the day2. Everyone was winning. When they "fixed it" NO ONE COULD WIN. Many upset people in the casino went to play slots and other games.
