Came with three girlfriends on a Saturday night in July. If you're a group of girls, it is IMPERATIVE that you contact a host beforehand to get on the guest list. We arrived at 9:30PM, waited in line for maybe 20 minutes, and then bypassed the line, got in for free, and got a free drink. I wouldn't go any other way.
This is the most impressive club I've ever been to. Its huge!! We ended up spending most of the evening outside by the pool where it was less crowded. There are tons of fans though so we never felt too hot (even though it was still 90 degrees). We're cheap girls (no table service for us!!) but there are tons of places to sit outside.
The clientele here is definitely a step above the other clubs in Vegas (we went to Chateau the night before). Most of the guys who approached us were well-dressed, polite, and not completely shit-faced. The music wasn't really to my taste (house music) but the dance floor was so crowded that I didn't really feel like trying to dance inside.
