I was there the same night as some event w/ Holly Madison, so I think it was extra busy. I didn't have to wait in line though, had pre-purchased my tickets, but the line was wrapped around the place.
I'm glad I didn't have to wait because I stayed all of 30 mins... this place would not be worth waiting an hour to get into. It's way too packed, even for its size. You can't get anywhere! And certain rooms are louder than others... which is cool... I guess?
It's a nice club, nice layout and design, but if you're with a big group you could def. get lost in here. Music was mish-mash... wasn't really a fan.
My biggest gripe, and this is with all clubs in vegas, is what's with the people smoking inside?! I guess I'm from Cali where we don't smoke inside ANYWHERE, but I just can't get my dance on next to someone and their cigarette butt!
