Seems like the really good ones retire or go to corporate. I think the good ones create an atmosphere with their activities staff that is engaging. It definitely enhances the experience. The bad ones…. Well are just dull and unimaginative. On a two week Hawaii cruise our cruise director Kirk Did a 1 hour gym class each day and even taught us a hula dance called the Hookilau. That was 15 years ago and I still remember his name.
