My ideal 14 day trip would be this:

Day 1-Arrive at Barajas, check into Hostal Adriano, take a nap and then eat tapas, drink wine, wander, shop and visit The Prado for 14 days. Hopefully GoMadrid, epaulino4 or another Madridman regular I know will be there and/or MadridMan will be having a party there during my stay.

Leading to...

Day 14-Return to Minneapolis with a suitcase full of La Casera, torrefacto coffee, conservas
and Manchego cheese.

Obviously I am kidding...I have already done this many times! Have a great time on your first visit to Spain!
