Does anyone know of any pornstars that will be dancing in Las Vegas this weekend, and if so where they dance at?

Try the Rhino.  During busy periods you can always run into a couple, models too.  I know Devon Michaels works at Crazy Horse.  The girls gravitate between the two.

I was going to say Spearmint Rhino- I heard a while ago that Inari Vachs was there regularly- also heard about Devon Michaels- not sure if they are still there

Tara Holiday dances days at the Rhino and Rio Lee bounces between both

I've seen Francine Dee at SRLV many times, but never have gotten dances.  Too plastic for me, but she seems very popular with a lot of other guys.  Good luck and enjoy.

Both Devon Michaels and Inari Vachs work at Cazy Horse according to their tweets

Feature or no, strip clubs always seemed to serve as a pit stop on the way to the hobby anyway. A couple of pricey, quick VIP dances and the result was maybe a little oral and finger fun (the club dancers I mean, not the features). May as well have thrown down for an hour and had the better menu in private setting. Unless the idea is to proposition feature dancers at the club. Even if you're really just interested in seeing them perform, you're gonna wanna make it rain (i.e. throw your money away).

Francine does not look too bad.  Sometimes plastic is good. LOL
