I have been to vegas a few different times and each time the club scene is for the most part off the hook. Check out Ra at The Luxor, saturdays are good but you need to find an afterhours cause it closes at like 4:00am. Lots of e-heads @ RA. Good music. Hip Hop/ Trance/House Also check out Drais @ Barbary Coast by Bally's Hotel. This place is more of a lounge but it goes till 8am, very dark cool place to chill. Good trance when i was there. Try and get to Rumjungle @ Mandalay Bay. This club is off the hook. Watch out for long lines though. if you are stayin at the hotel, you can bypass the line and get a discount on admission to the club if not free admission, i dont remember. Also your best bet is to search under Las Vegas on clubplanet.com, Once you click vegas then click club search and it will give you alist of all the hot and not so hot places to go clubbing in vegas. Just as a heads up, not much goes on weeknights, clubwise, but ask your taxi driver when you get there, they always knew what was going on the night of and always had somewhere for me to head to. Good Luck! Have fun in vegas!
