Stayed in the cosmopolitan, not only did I get to go in for free but I gotta skip the huge lines as well. :) Dj politik was performing, he started Spinning  at 1130 and then stay throughout the whole night. It was a blast! Confetti being bursted every 30 mins, cold air blast on a crowed dance floor perfect!  Bartenders are friendly, 15 dollar drink average but were nice ladies. Oh and if you are going to complain about no room, obviously you are no baller who can not afford table service. Enjoy life, dance elbows with strangers, I don't care if people are stepping on my feet, and if I step on yours no worries, I'm wearing flats. :P I'm there for the music and dancing.Overall great experience and if you are drinking, if you don't want them spilled just drink them at the bar. :P
