Me and my friends are planning to travel through France, Spain and Portugal in our summer holidays. Because we're from southern Germany we'd like to reach Paris the first day by starting at Stuttgart. We heard that taking the TGV and ordering the tickets in France is the cheapest way.
So our question is, what is the cheapest (and fastest) way to travel from Stuttgart to Paris with a global Interrail ticket?
Links are welcome, too.
Thanks in advance, Olli91.
