Marquee Dayclub kicks off its grand reopening with Dutch electronic music powerhouse Martin Garrix taking over the decks alongside Justin Mylo. The 22,000 square-foot venue at The Cosmopolitan transforms into a sun-soaked celebration, where the pool becomes the dance floor and the energy rivals any nighttime performance. Garrix, known for chart-topping hits and festival-headlining sets, brings his signature progressive house sound to the daylight hours, creating that unique Vegas atmosphere where champagne bottles pop under blue skies and the music pulses through the afternoon.

The reopening weekend draws the kind of crowd that knows what they're looking for—serious electronic music fans mixed with those chasing the quintessential Vegas pool party vibe. With Justin Mylo complementing the lineup, expect a full spectrum of electronic sounds from melodic builds to heavy drops. The venue's two pools and multiple levels mean you can choose your own adventure, whether that's front and center at the DJ booth or lounging in one of those cabanas with the infinity edge dipping pools. Entry is available through general admission or table reservations, and this is strictly a 21+ affair.
