I finally have my itinerary planned, but am now wondering...We are staying in Marbella the last week of March, then traveling around for another 9 days. We have been planning to visit Granada & the Alhambra as a long day trip from Marbella. Is this realistic? Fodorites seem to feel this is way too far to drive, but I'm guessing Madrid Manites (Madrid Manions?) may be a hardier crowd. Any opinions? Thanks!
