Marquee Dayclub turns into Vegas's quintessential pool party backdrop for Poolside Sundays with DJ Puffy spinning the soundtrack. Picture sun-soaked afternoons where the beats merge seamlessly with splashing water and clinking cocktails, all set against the backdrop of The Cosmopolitan's multilevel entertainment complex. The two pools and gaming area create a layout that lets you move between dancing, lounging, and socializing without missing a beat.

Grand cabanas with infinity-edge dipping pools offer a more private vantage point if you're looking to post up with a group, complete with dedicated food and cocktail service so you don't have to leave your spot to stay refreshed. Whether you're grabbing a table or coming through on general admission, the energy stays consistent—sun, music, and the kind of crowd that knows how to make a Sunday feel like an event. The specialty food and drink menu rounds things out, giving you something to sip on between dips in the pool or stretches of dancing in the sun.
