Oyster's Guide To Spain In 6 Days (PHOTOS)

Visiting our neighbors "across the pond" isn't just a hop, skip and a jump that the saying makes it sound: It involves long (and expensive) flights, long lines in customs, and plenty of seat-of-your-pants transfers and transactions. But Europe is a lifetime must-see and Spain is one of its most diverse and fascinating countries.

So how do you possibly see all it has to offer during a week-long vacay? Well, the reliable, high-speed AVE trains certainly help. The country's top destinations -- Barcelona, Madrid and Seville -- are all within 3 hours of each other by way of the AVE, which makes it easy and fast to discover this trio of cities in just one trip. Of course you could spend years in the country and still be discovering new spots each day, but our Oyster guide offers a solid itinerary for each city that includes the three attractions you just can't miss -- and still allows you enough time to enjoy some tapas al fresco.

And, as hotel experts, we let you know the best places to stay, to boot. Pack your bags -- and don't forget this guide! You're Spain-bound, baby.
