T-Mobile Arena hosts UFC 335, bringing a title fight and a full undercard of championship-caliber matchups to one of the city's premier sports venues, with energy building toward a can't-miss main event. Over at MGM Grand, Hakkasan Nightclub turns the decks over to Snoop Dogg for a one-night takeover, mixing decades of hip-hop classics with the club's signature multi-level party atmosphere. And at The Cosmopolitan, Marquee Dayclub's Halloween weekend edition of Dawn 2 Dusk features Martin Garrix, whose festival-sized sound will fill the pool deck with bass and energy under the desert sun. Costumes, cabanas, and crowds ready to move make this one a standout on an already packed weekend.
