Sundays at Marquee Dayclub take on a different energy with Jerzy behind the decks, soundtracking an afternoon spent between the pool and the party. The space itself does a lot of the work here—two pools, grand cabanas with their own dipping pools, and a layout that lets you choose between lounging poolside or getting into the thick of the crowd near the DJ booth. Sun, music, and the general buzz of a Vegas day party all blend together under the open sky at The Cosmopolitan.

Table reservations get you a dedicated spot with service, while general admission keeps things flexible if you'd rather roam between the bars, the gaming area, and the pool decks. Either way, it's a daytime scene built around good music, cold drinks, and the kind of lazy-but-lively atmosphere that defines a proper Vegas pool party. Must be 21 or older to get in.
