Marquee Dayclub turns into a sun-soaked playground for its Halloween Weekend gathering, with DJ Brooke Evers taking over the decks amid the pools and cabanas of The Cosmopolitan's signature outdoor space. Expect the usual mix of house and dance beats echoing off the water as the crowd mingles between the two pools, whether they're floating in the infinity-edge cabana dips or dancing barefoot on the deck.

The Halloween timing adds a layer of costume-fueled energy to the day, with guests likely leaning into playful, sun-friendly takes on their favorite spooky looks. Between sets, there's plenty to do—grab a specialty cocktail, snack on poolside fare, or just soak in the desert sun while the party builds around you. It's a daytime scene that blends the glamour Marquee is known for with a looser, holiday-inspired vibe.
