Halloween weekend gets a festival-sized jolt when Martin Garrix takes over Marquee Dayclub's pool deck on October 31, blending big-room electronic sound with the venue's sun-soaked cabanas and infinity-edge pools. That same night, Hakkasan Nightclub hosts a rare treat as Snoop Dogg steps behind the decks, bringing decades of hip-hop favorites and his signature West Coast charisma to the MGM Grand's layered dance floor and VIP tables. Closing out the year, Steve Aoki returns to Omnia Nightclub for a New Year's Eve celebration beneath the venue's iconic chandelier, mixing electro house and pop remixes as the countdown to midnight builds toward a citywide celebration. Together, these three nights capture the range of Las Vegas nightlife, from daytime pool parties to legendary DJ sets ringing in a new year.
