Fashion mavens and wannabes now splash and lounge where Esther Williams once fluttered and kicked in lavish synchronized-swimming numbers. Decades later the faux tropical lagoon remains the coolest place to be seen cooling off in Miami. A shallow ledge hugs the pool's Moroccan-style curves so you can immerse yourself in this chlorinated oasis without mussing your hair. Dive into the deep end or stand beneath the waterfall while sheets of water pummel your back. Sneak in after dark for a late-night dip -- you'll think you fell into paradise. Hotel guests swim for free any time; visitors pay fifteen bucks and are ejected after seven at night.
