Once a career graveyard for crooners like the Rat Pack, Vegas has had a personality overhaul. Sure, there are more slots and card tables than you can shake a stick at, but the non-casino entertainment is now all about those repetitive beats (hence the 58 place hike in this poll!). Encore Beach Club, as it is called by day (before it turns into Surrender after sundown), is connected to the luxurious Wynn Hotel and is host to some of the hottest DJ talent on the strip. Everyone from Pete Tong, Afrojack, Calvin Harris and Chuckie have been seen smashing out beats to the bikini-clad beauties who gyrate in the pools, frolic on the floating beds and group in numbers among the champagne-fuelled cabanas that surround this epic venue. Large, loud and proud, Encore is a symbol of the Vegas transformation - an essential visit - just don't forget your suncream!
