For a few months each year, brave (or well-lubricated) souls can feasibly attend a Marquee Dayclub party, squeeze in a disco nap, resume partying inside the nightclub, then witness the bash transform from EDM extravaganza to a more underground affair and boogie down until sunrise to a world-famous DJ at afterhours. It’s the nightlife equivalent of getting your three squares a day. Cosmopolitan, 702-333-9000. Nightclub: Mon, Fri & Sat, 10 p.m.-5 a.m.; dayclub: Fri-Sun, doors at 11 a.m., cover varies.
