love train

just make sure you are the engine and not the caboose..

activities and they are definitely a "YMMV" type of thing!  How fun/hot/enjoyable it is will depend upon any number of factors: the number of women who are there; the girl-to-guy ratio, how cool the other dudes are (yes, people can get downright rude when the testosterone starts flowing); the skill level of the girl(s) and their enthusiasm or lack thereof!   The ones that stick in my mind involved a women named "Bubbles" (who did an "American Bukkake" once) years ago who would set up shop at a swing club called The Panther Palace (I think, I was drinking a lot back then!) and would blow any guy who stepped up to the plate!  The "Bubbles" thing came from her only request being that you had to nut in her mouth so she could blow bubbles with the cum!  It was a spectacle, if nothing else!  There was one time where she and her friends had to have blown at least 75 guys!  That said, she did know how to suck a dick and if you were patient, when it came your turn, you got her full attention for awhile or until you came!

That said, if I were you, I'd go, having zero expectations, planning on just watching but if the mood strikes you, jump in!  My only (very few) regrets I have in my life are opportunities foregone!
