Thanks for the great advice everyone!! This has been immensely helpful.

Right now we're leaning towards renting a car + driving north through the Pyrenees (thanks jib71!). We're thinking about working our way towards either Nice (~6 hr drive, according to Google) or Bordeaux (~6 hr drive) to see some countryside & do some wine tasting. Does anyone have any recommendations? Or any advice about renting/driving in Spain (what should we expect for <25 year old driver fees)?

(dragonfirebcn & LapLap - Don't worry! I think we're going to go Sunday -> Thursday now, rather than miss a Saturday in BCN!).

Last question - It looks like F.C. Barcelona has a home match on 3/22. I'm not the biggest soccer (err, football) fan, but I've always wanted to experience the drinking/singing/wildness of European soccer. Should I expect this kind of crazyness if we go to the game (and would I be able to get tickets)?

Thanks!!
