Planning on Spain

I'm knee deep in planning our upcoming trip to Spain and finding it all very difficult. This country frustrates all my attempts to plan out a logical route. It doesn't help that we are flying into and out of Madrid which lies smack in the middle of the country.

The distance between some places makes some travel times prohibitive. I've all ready had to make the decision that Santiago de Compostela is just to far away to logically fit in. That does frees up a couple of days for other places though.

Also, my parents are meeting us there for the first week or so, which means I have to coordinate with their schedules as well.

I have never had this much trouble trying to map out a route before. If anybody has any suggestions, please feel free to pass them along.
