Marquee Nightclub & Dayclub on Wednesdays

Marquee Nightclub & Dayclub at The Cosmopolitan is the venue that invented the Las Vegas dayclub concept in 2010 and still sets the standard 15 years later. The nightclub spans 40,000 square feet across three distinctly programmed rooms: the newly renovated Main Room anchored by a 1.5-ton high-resolution LED monolith centerpiece and state-of-the-art laser systems, the Boom Box for bass-heavy electronic and house sets, and the Library speakeasy-style lounge for a more intimate VIP experience — all served by seven individual bars. The 5,000-person capacity venue is operated by Tao Group and books the best of tech-house, EDM, and open format through the year. The 2026 resident roster is headlined by Fisher and Chris Lake, joined by DJ Pauly D, DJ Mustard, Deorro, Nora En Pure, Sam Feldt, Lost Kings, CID, and Eric Dlux. When the nightclub closes, the rooftop Marquee Dayclub opens each spring and summer with a poolside stage, Strip views, and the same world-class DJ programming in the afternoon sun. For guests staying at The Cosmopolitan, the club is a direct elevator ride from your room. The Library speakeasy — the smallest of the three rooms — operates as a reservation-only bottle service space for groups of 4–8 who want an intimate experience: low lighting, book-lined walls, and a private-feeling atmosphere that exists 50 feet from the 5,000-person main room. The Boom Box room is designed specifically for audio performance: lower ceilings, an enclosed acoustic environment, and a sound system tuned for bass-forward tech house and electronic production. Monday nights — Marquee Mondays — have been the club's signature industry event since 2010, consistently drawing the best mixed-demographic crowd of any night in the building and remaining one of the most reliable midweek club nights on the entire Strip. The Cosmopolitan's center-Strip position means the guest list entrance is walkable from ARIA, Bellagio, and the Park area, making it the most geographically accessible mega-club on the Strip for guests without a specific hotel anchor. With a capacity of approximately 5,000 guests, Marquee Nightclub & Dayclub is a sprawling mega-venue that delivers festival-grade production inside an enclosed space, with multiple zones and levels that each carry their own distinct atmosphere.
