Think of Wet Republic, the city's biggest 'ultra pool,' as a nightclub brought out into the sunlight. The mostly 20- and 30-something crowd in stylish swimwear show up for EDM tunes spun by megawatt DJs like Calvin Harris, fruity cocktails and bobbing oh-so-coolly around saltwater pools while checking out the bikini-clad scenery. Book ahead for VIP bungalows, daybeds and cabanas.
