Want 24-hour partying? Here's the place, which revolutionized the Miami party scene over a decade ago and still gets accolades as one of the country's best dance clubs. But depending on the month, Space wavers between trendy and empty, so make sure you get the up-to-date scoop from your hotel concierge. Created from four downtown warehouses, it has two levels (one blasts house music; the other reverberates with hip-hop), an outdoor patio, a New York–style industrial look, and a 24-hour liquor license. It's open on weekends only, and you'll need to look good to be allowed past the velvet ropes. Note that the crowd can sometimes be sketchy, and take caution walking around the surrounding neighborhood.
