It is a club that's been around for a while, but I had a great time there! There was a huge line already at about 10, but a person I went with bought a 'front of the line pass' online and after finally finding the right guy to show it to, we went right it. It's always the guy with the clipboard, I shoulda known!
Inside the club was fun. It was packed pretty hard, as I kept getting bumped into by everyone else on the dance floor. Drinks are average price for a Vegas club, ~10 bucks a good drink.
I am not sure why it's called Rain. Maybe because I wish it did. It gets pretty hot when you are dancing drunk with everyone else's body heat on ya, and to top that off, above the dance floor, there are huge flame throwers that shoot out random fireballs that kinda scorch your face if you are right under them. I needed some Rain then!
