Marquee Dayclub kicks off its pool season with DJ E-Rock taking over the decks for the grand opening weekend celebration. The 22,000 square-foot dayclub at The Cosmopolitan comes alive with two pools reflecting the desert sun, multiple bars serving up specialty cocktails, and the kind of energy that makes Vegas pool parties what they are. E-Rock's sound fills the space as guests lounge in cabanas or claim their spots poolside, the music mixing with splashing water and conversations that flow as freely as the drinks.

The grand cabanas offer those infinity edge glass dipping pools and dedicated service if you're looking for something more exclusive, while the gaming area provides a Vegas-specific twist to the typical dayclub setup. Entry is available through table reservations or general admission, though you'll need to be 21 or older to join. It's the kind of Sunday that stretches from late morning into afternoon, where the party mindset takes over and the usual weekend rules don't quite apply.
