If you're a group of girls your odds are better, but if you're not a certain definition of hot, you're never getting in. Or, worse, a doorman will point to three of you and say, "You three can come in. The rest… hell no!" This actually happens. Nightly.
Either plan ahead through a promoter, or be prepared to wait outside for a very, very long time. Getting there early (like before midnight) helps too, but if you don't look the part or have the money, you might wait out there all night.
Flying into Fort Lauderdale (FLL)
Miamians love nothing more than that friend who says, "Hey, can you pick me up at the airport Friday morning?" and then ever-so-conveniently texts, as they're boarding the plane, "You know I'm flying into FLL right?"
You might get all giddy because you saved $75 by flying into Fort Lauderdale instead of Miami. Easy there Turbo, it's still gonna cost you. A cab from FLL to South Beach will run $100 each way, while Uber or Lyft is about $50-$60. If you arrive during rush hour (7-10am on weekdays) that can triple, and you'll spend the first two hours of your vacation in traffic. Even without traffic, that drive is 45 minutes.
