Go see Todd the cruise director and ask him if he is still doing his late night "Improv" show. When we wen tin october, Todd and several other entertainment staff members put on their own show, it was great. You would have a great time participating if he is still doing it.
(Assuming of course Todd is still the CD, I'm not sure how long their contracts run)
The same group also did a murder mystery.. go for that too.
