We were on Oasis last week. It was our third cruise on Oasis, 15th on Royal. The ice show and Aqua 80 (diving) shows are not to be missed. The headliners change weekly. One night we had a singer who only sang Adele songs. She was excellent. The music hall had a Styx cover band that played all week and was also excellent. The adult comedy show was so so. I've seen funnier comedians, but they also change weekly. We did not go to see Cats. We live 30 minutes from NYC and I go to Broadway shows often. Had no interest in seeing Cats.
