I believe it's more commonly referred to as AVN, check the Vegas and Porn Star boards. And yes, I've been, but I prefer the extra  activities, like the AVN M&Gs held during the week and seeing porn stars who escort on the side plus all the touring escorts who come to party in Vegas as well. The actual show is kind of tame, compared to all the other stuff.  It's at the Hard Rock for the first time, so it's going to be interesting to see what happens.
