I'm planning a trip w/ the fiance to France (Paris -> Avignon -> Bordeaux -> Paris) and taking the TGV to get to those places (with the exception of Avignon -> Bordeaux).The official website for North American's to buy train tickets is raileurope.caHowever, I have heard that you can purchase (cheaper) tickets from the European website if you select a European coutry as your location. Has anyone done this before?
