Marquee Dayclub at The Cosmopolitan of Las Vegas

3,500+ estimated attendees

Martin Garrix headlines Marquee Dayclub at The Cosmopolitan of Las Vegas on Saturday, October 31, 2026 — Halloween Day — beginning at 11:00 AM. Martijn Garritsen's October 31 Marquee Dayclub booking places the three-time DJ Mag #1 DJ (2016-2018) in an unusual context: a daytime outdoor pool performance in costumes on Halloween morning, where the progressive big-room house architecture of his festival catalog — Animals, In the Name of Love with Bebe Rexha, Scared to Be Lonely with Dua Lipa — operates against direct Las Vegas autumn sun rather than the laser rigs and indoor darkness that define his OMNIA Nightclub residency. Marquee Dayclub's rooftop position at The Cosmopolitan places it mid-Strip between Aria and Bellagio, drawing foot traffic from the densest hotel corridor on Las Vegas Boulevard. Halloween Dayclub events at Marquee carry costume themes that create crowd energy distinct from standard pool season programming — a costumed daytime crowd with festival-ready energy creates a context for his big-room buildups that differs meaningfully from the summer Saturday daytime format. Guest list through NoCoverVegas covers general admission entry for qualifying groups.
