We know what you're thinking: Tanning salons are not cool. Many believe that they help cause cancer. Well, screw you -- we look way better with a little color. And for that, we recommend Tan World, where, as the slogan goes, "tan lines are optional." The staff is genuinely nice, and the beds are strangely comfortable. But the Mystic Tan booth is where it's at. Yeah, that first shot of bronzed goodness is f-ing cold, but if you can hack holding your breath for 30 seconds and don't mind smelling unpleasant for a few hours, you're golden. Literally.
