Miami (FL) doesn't close. When I lived there not long ago, there was a period where I was between jobs where I came home after sunrise every day of the week. If you're trying to stay out past 2am in Miami and not able to, you're not trying... at all. Bars/clubs usually close at 5am, but I believe are only required to close for 1 hour a day, so there are afterhours spots.
