I live in Vegas. I train at Shine Alternative Fitness and recommend it highly. I train mostly with Suwasit but there are other great teachers there, as well (including Jenyne Butterfly). Also, you can try other things while you're there that might be new to you; aerial hoop, aerial silks, hand balancing, antigravity yoga, flexibility training. I've done the hand balancing class a few times. The other classes I take regularly.
I also teach Stripper 101. I love our class, it is a ton of fun! Just to let you know, the pole part of class is an intro for beginners, most women who visit our class have never been on a pole. The most difficult move we will execute will be a fireman spin (maybe a front hook if you're a natural! hehe). There will also be focus on sexy non-technical pole moves like booty clapping & body waves. We go over lap dance and I think you will enjoy that a lot no matter what pole level you're at.
As far as shows, the Michael Jackson One show was already mentioned & has Jenyne. I don't know if Zumanity has pole at the moment, you may want to check. But that's a great show either way :)
If you're thinking of hitting the strip clubs, it's a gamble. Remember that dancers in Vegas (I don't know how it is anywhere else) make most of their money in lap dance, not on the pole. So you may or may not see anyone do anything technical at all if you go. I've been to almost every strip club in town and seen only a handful of girls who were doing interesting tricks. Again, it's not what makes them money so...I still find the clubs fun, but I don't walk in expecting technical pole prowess.
Hope this helps, enjoy your stay in Fabulous Las Vegas ;)
