I spent some time in Andalcia a few years ago, but it doesn't look like you're going to be in the area I was. The picture below is the cathedral in Cadiz, which is an interesting little town,originally Roman (Cades), and the site of the battle of Trafalger, or more acurately, where most of the fleet is now.
If you get a chance to swing through there, it's worth a bit of time.
