I'm not a man, but my husband didn't have a bachelor party. We pretty much just decided to get married and did it.
But some clean ideas could be a comedy club, paint ball, amusement park, poker game, a cook out, a concert, ect. ect.
I'd imagine you are trying to avoid bars and strip joints... Nice to know there are more people out there who don't think its right for a man thats getting married to be wasted at a strip joint!
