A friend who travelled recently to Granada passed on some practical advice.
First, be aware that the traffic is very slow at all hours of the day, and that it is not easy to reach the Alhambra if you
don't know the area and are driving. His advice: park your car at the airport outside of town, and take a taxi
to the center of town or straight to the Alhambra.
He reported that a number of travellers found the auditape at the Alhambra, all
taken from the writings of Washington Irving, as tedious. Get a guidebook, but don't bother with the tape.
