Marquee Dayclub kicks off its season with DJ E-Rock spinning poolside as part of the Grand Reopening Weekend celebration. The 22,000 square-foot venue brings back its signature blend of electronic beats, two sparkling pools, and that unmistakable energy that comes with Vegas dayclub season starting up again. E-Rock's selections typically lean into house and hip-hop blends that keep the crowd moving between dips in the pool and lounging under the desert sun.

The multi-level space at The Cosmopolitan offers plenty of room to find your vibe, whether that's dancing near the DJ booth or claiming a spot by one of the pools. The cabanas feature those distinctive infinity-edge glass dipping pools if you're looking for something more elevated, while the main pool area keeps things lively with the music pumping through high-quality sound systems. The gaming area adds an unexpected Vegas twist to the typical dayclub setup.

Entry works through either general admission or table reservations, and you'll need to be 21 or older to attend. The Poolside Sundays series runs throughout the season, making this grand reopening the first of many sun-soaked afternoons ahead.
