Poolside Sundays brings its usual mix of sun, music, and crowd energy to Marquee Dayclub, and this edition lands on race weekend, when the city fills up with extra buzz and a crowd ready to celebrate. Expect the pool deck at The Cosmopolitan to be in full swing, with DJ Crespo keeping the rhythm going as cabana guests sip cocktails and float between the two pools. The multilevel space gives plenty of room to post up on a lounger, dip into one of the infinity-edge cabana pools, or just wander the deck taking in the scene.

The vibe leans toward lively but relaxed daytime partying, the kind where the music builds steadily as the afternoon wears on and the Vegas sun does its part. With race weekend energy in the air, the crowd tends to be a little more charged up than usual, mixing racing fans, locals, and visitors all looking to soak up a day by the water before the city's nightlife takes over.
