Cancun is Mexico's party capital, and this night out will give you a great introduction to its explosive clubbing scene. It takes place at Señor Frog's, a well-known bar-come-restaurant that majors in food and fiestas. The dress code for the evening is bright white, in preparation for the main event :a glow-paint fight just after midnight. There's an open bar, so you can enjoy all the cocktails you want. And if you can tear yourself away from the huge dancefloor, try out the waterslide, which weaves across the restaurant and into a warm lagoon right outside.
