Nightlife impresario Victor Drai ruled the underground—literally—in Las Vegas. His after-hours club (which still exists in the underbelly of The Cromwell) was around for nearly 2 decades as one of the only house-music-fueled after-parties, with attendees who often spilled back on to the Strip when the sun was already well up in the sky. Now the sunlight shines on Drai’s all day long at his 65,000-square-foot rooftop club atop The Cromwell, which hosts the beach club around the hotel pool until the sun goes down, when it transitions into a dance club. A roster of well-known resident DJs provide the EDM-heavy soundtrack, but hip hop acts such as Nas, Nelly and Fat Joe have been making their way into the residential rotation as well. The dress code still applies here—even if you’ve been hanging out at the pool party all day, you still have to put on more clothes to attend the club at night. The nightclub is open Thursday through Sunday from 10:30pm until 4am.
