Washington, D.C.

Henry Kissinger once said, "Power is the greatest aphrodisiac," and if you subscribe to that theory, there's no better place for a singles vacation than Washington, D.C., where love and politics converge. Democrats and Republicans alike debate (and flirt) over drinks everywhere from intimate lounges to rowdy sports bars, while the capital's monuments and museums make for romantic backdrops when lit up at night. With a tantalizing mix of transplants from all over the U.S. and abroad, you're sure to make some interesting -- and hopefully high-powered -- connections.
