As I'm working through an itinerary I'm looking at splitting Spain into two halves:
Northern Half- Barcelona, San Sebastian, Bilbao, Madrid/Segovia
Southern Half- Toledo, Grenada, Cordoba, Sevilla, Gibraltar
Is one half better to use a rental car and the other better served traveling via train? Flights are in/out of Barcelona.
I understand that Grenada is not connected to the main train system(?) thinking rental car might be better in the Southern half of the country...?
