Unhappy with bachelorette party - alternatives?

Well, if you trust your fiancee but don't trust her friends, then you have nothing to worry about. I'm sure your fiancee is smart enough to put her foot down when things get too much out of hand. I say you just let her be with her friends. If they go against what she really wants, then it's time for her to get new friends. Friends should respect each others wishes, to the fullest. But, if that really bothers you, have them go out to a restaurant. It's impossible for dancers to be there half dressed in public.
