I want to buy a France/Spain train pass...but for the life of me can't get info on how to get from Marseille to Valencia other than one can get to Montpellier where I guess there's a direct train the rest of the way. I don't know if I can upgrade my pass with a single supplement to take what I think will now be a TGV train. The snfc.com site can't give info for Spring '13 , ditto tgv-europe. Anyone ever done this. I will be at the Marseille airport and the flight is chere. Plus I'd rather see the countryside. Do we have travel agents in the US that are willing to handle this little mickey mouse purchase?
