With its gold-plated chandeliers, gold-embossed crocodile VIP booths and even a gold bas-relief of actual employees this club at Encore is a tribute to the wonderful, ahem, excess that is Las Vegas. During the day, it opens up to a massive pool area for hotel guests, who can order bottle service in its cabanas. Sunday nights in the scorching summer are when night owls head to its (literally) cooler after-dark pool party, Night Swim at XS. You can party in the pool, play a hand of blackjack at one of the outdoor tables, or rent one of 26 cabanas to party more privately. Some of the best DJs in the business play here, like AVICII, Kaskade and ZEDD.
