NOTE.... I prefer not to rent a car because of parking, old city limitations, skinny streets, one ways and difficulty with language / signage. ETC Not even if I'm picking it up at the airport and trying to leave the city right away.
We love trains! Especially the modern clean fast ones in first class. But any train works for less than a few hours. No interest in night trains. We'd mostly book trains for around 10AM - noon between cities. We carry one RS style back pack per person. No suit cases.
Im not sure how to deal with getting to Granada, a mountain town or a coastal village and back to Seville. But, I can move any piece except the front end stop in Madrid and the back end stop in Barcelona.
Here is our itinerary. I don't have anything booked except my air from the US to Spain.
