Are the teen clubs on cruise ships fun or lame?

I'm sixteen, and this summer i'm going on a cruise to bermuda for a week on the norwegian dawn cruise ship and i read about some teen club thing they have that hosts dances for teens at night. i'm going with a friend who's also sixteen, and we were both wondering if said club was fun or if it was a waste of time. so pretty much, if you could tell me about the dances at night and the activites and the clubs in general, that'd be really great. thanks!
