Remember how much fun sleepovers were when you were a kid? Take you and your friends back to that time and trade in your shorts and flip-flops for pajamas (extra points for tropical pajamas). Ask friends to bring sleeping bags, flashlights and snacks. Invite them over, turn out the lights and pass out the drinks. You can even head outside in the yard with some tents to make it a camping theme. It's fun to be a kid again, so go on and huddle up next to your friends for a blast from the past.
