XS is part of the Wynn hotel and entertainment complex in Vegas, conjoined to Surrender/Encore Beach Club, but it's so palatial that it requires a stand-alone entry of its own.

Essentially a massive ballroom with a huge chandelier and mirror-balls hanging from the ceiling, and various chi-chi VIP table areas situated just off the side of the dancefloor, the clue is in the name for clubbers wanting to party here.

David Guetta has his exclusive Vegas residency here, playing virtually every week, while Avicii, Martin Solveig and Wolfgang Gartner also play several times every month.
