I am so excited that I was able to successfully purchase train tickets from the Renfe site. Thanks to much help from everyone at T.A. I keep debating between trains for the whole trip versus renting a car for part of the time while in Andalucia. Since we have only 8 nights total (4/Madrid & 2/Sevilla & 2/Puerto de Santa Maria, I am sort of leaning towards trains for the whole trip. I think that the car might be more frustrating and actually take us more time. If I decide to use all trains, I have found another web fare for part of the trip which I would buy. I am wondering whether the other regularly priced tickets can just be purchased at the station or if I should buy all of them now. The regularly priced tickets are from Sevilla to P.S.M. and P.S.M. to Cordoba. Any thoughts?
