Yes, we were disappointed because the driver, who was so highly recommended on the boards (I did not arrange this one - someone else did), and was from England, was touted as a tour guide and our feelings were that he was not more than a driver. Then we found he needed to be licensed. That is one of the issues when you book many thousands of miles away. One of the advantages of using Regent's excursions.
Inside the Alhambra, you need their guides and they had that as well as the recorded guides available.
