We are going on an 8 week trip to Spain and besides the Alhambra, what sites are best done with a guide (as opposed to an audio guide, guidebook, tour app). We're not usually tour guide people but we also don't know a lot about history in the places we're visiting.
We will be in Toledo, Cadiz, Seville, Cordoba, Granada, Salamanca, Segovia, Burgos, Bilbao, San Sebastian, Zaragoza, Valencia.
I appreciate any suggestions!
