My fiance and I are marrying in Paris in November. My future father-in-law and his wife plan to travel to Barcelona, arriving BCN on Sunday 8 Nov. They must be in Paris for our wedding on Thursday 12 Nov. Originally they planned to take Rail Europe (8 or 12 hour options) from Barcelona to Paris. I'd like to provide them with an alternative that allows them to see more of France than from inside a train. Are there trains between Barcelona and France that they can get off and on over 3 days and, if so, what are the best stops and places to explore en route? Also, if they opt to rent a car, what is the best route to take that will allow them to stop and explore? On the suggested auto route, what areas would you suggest they explore?
I appreciate everyone's input.
Thanks!
