It's against the TOS (Terms of Service) here and on most cruise boards to mention the name of another board. That's why I said "another"!
I'm not at all sure
, but I think that if you have your SAG card (or whatever the equivalent is in your profession) you're not allowed to participate in the talent show.
The best idea, IMO, would be to go sign up and see what the rules are. They very well may allow you to perform as a "special" performer if you show them your professional card.
It really wouldn't be fair for you to compete (and I know you don't care about winning) with us "non-professionals"
! (Not that I
would ever get on stage and do anything
!) I'm amazed at the number of talented passengers we see in the talent shows!
