Memorial Day Weekend at Marquee Dayclub brings that perfect holiday party energy to The Cosmopolitan's rooftop paradise. The 22,000 square-foot venue transforms into a sun-soaked celebration with two pools packed with people looking to kick off summer in style. The DJ booth pulses with electronic beats while guests drift between the water, the bars, and the gaming area, creating that mix of pool party and club atmosphere that Marquee does so well.

The grand cabanas with their infinity edge dipping pools offer a more exclusive vibe for those wanting their own space, complete with bottle service and dedicated staff. But the real draw is the collective energy of a holiday weekend crowd – people are in that three-day weekend mood, the weather's heating up, and the party stretches from late morning into the evening. It's the kind of Sunday where you're not worried about Monday morning because, well, there isn't one.
