Marquee Dayclub transforms into a festive celebration of Cinco de Mayo weekend with Poolside Sundays taking on extra flair. The 22,000 square-foot venue becomes a sun-soaked fiesta where the usual dayclub energy meets holiday spirit. Expect the signature Marquee experience with resident DJs spinning electronic beats across two pools, while the crowd lounges in cabanas or dances poolside under the Las Vegas sun.

The venue's grand cabanas with their infinity edge glass dipping pools offer a more exclusive way to enjoy the festivities, complete with dedicated cocktail service and views over the entire scene. Multiple bars keep the specialty cocktails flowing throughout the day, and the gaming area adds another layer of entertainment beyond the pools. The holiday weekend timing means the usual Poolside Sunday crowd will likely be even more energized, mixing locals and visitors looking to celebrate in true Vegas style—swimwear, sunglasses, and the beats echoing off The Cosmopolitan's towers.
