4. New Orleans, Louisiana
The food alone will make you throw anything into a suitcase and race down here. There are rows and rows of restaurants that will throw you back into the early 1900's and make you feel like a southern belle. And when you're not busy eating, you and your betrothed can nip into classy bars and listen to soul-stirring jazz and blues. The nightlife can be as relaxed or rowdy as you want it to be, and there are a bevvy of fun tours you can participate in when you want to get lost in culture for an afternoon. (Examples are plantation tours and ghost tours!)
