Suggestions for nightclubs in Vegas?

I am turning 21 this week, and (of course) am going to Vegas. It is going to be me, my sister, and two of my best girl friends. Any suggestions for the best places to go for a good time?

Don't go to Voodoo Lounge at the Rio, it's mostly full of older people, and if you are turning 21 it will suck unless your goal is to party with divorced people in their 40s.

I suggest Body English at The Hard Rock and Moon at The Palms. They always seem to have great DJs and a classy younger crowd.

You are lucky that it's all girls in your group because it will be easy to get in anywhere.

I personally think the best website to learn more about Vegas clubbing is:
www.jackcolton.com
That site reviews all the major clubs and has tips for getting in. It's very blunt and honest, plus, they don't sell anything on the site (passes, tickets, etc) so it's not as biased as other Vegas sites that are trying to sell you on a particular club.

The RIO - oh they have a free floor show almost every hour, for alot of free entertainment and hot times upstairs at the bar - the RIO is the place to go!

The Palm has great night clubs, Body English, LAX, Hard Rock.... the possibilities are endless.

This site will give you info on all of the nightclubs in LV
