Size matters. And on Memorial Day weekend 2010, a new venue at Encore changed the game in the Las Vegas club-life, proving exactly how much it matters. By day, Encore Beach Club is a luxurious 45,000-square-foot Mediterranean-inspired oasis with three tiered pools, 26 cabanas, and daybeds and lily pads where the beautiful people frolic. But when the sun goes down, the sexy, intimate 15,000-square-foot adjacent Surrender Nightclub throws open its glass wall to the Beach Club to create a 60,000-square-foot behemoth indoor/outdoor club. When the stars light your dance floor, who needs a roof?
