*non-stop* Madrid at $489 RT from Philadelphia

Hola and welcome to the city that never sleeps!

Okay, yes, technically that nickname is already taken. But between its late-night flamenco shows and nocturnal café scene, Madrid can easily keep you buzzing all night long. Don't sleep too late the next morning, though, or you'll miss out on daytime delights like the El Rastro flea market.

If the hustle and bustle does become a bit much, simply find yourself an oasis of calm in a stately museum or indoor jungle before moving on to the next thrill.

After all, you can always catch up on ZZZs during the flight home
