We will be in Marbella for a week at the end of March, then travelling for another 8 or 9 days. Given the distance, jet lag, etc. I'm thinking we might take a train from Madrid to Malaga, and get a car there. After the first week, we could return the car to Malaga, take a train to Sevilla to explore for a couple day (sans car); then rent a car in Sevilla & continue North (Toledo, Avila, Segovia?) staying in small towns; then return the car in Madrid and spend 2 - 3 days there without a car. Is this a workable plan or too unwieldy, expensive, etc.? Any input would be appreciated!
