We saw Alan Ball (I think that is how he spells it) on the Inspiration this summer. He does a cleaned up version that you can bring the kids to and then an adult only version. Very, very funny man. Looking at his website, it appears he does a lot of Carnival cruises so if he is on the one you are going on, definitely check him out. Get there early for a seat though.
