Vegas is a very different experience for guys and girls as well. I remember I was seeing this Brazilian girl who was living in Toronto. She went to Vegas for the weekend with some other expat friends and was telling me. "Oh ya we were waiting in line for the club and some guy came out of the front door and noticed us and brought us in. Apparently he was some football player, Jimmy Garapollo or something?"
They partied with the 49ers and didn't spend a dime all night.
I've been to Vegas once, and the parties were fun, but paying $1,000 between a group of 5 guys to get in anywhere gets old.
