Is it possible to take the tgv from Paris to Strasburg without any connections and then rent a car at the Strasburg train station to drive 2-3 weeks through france, dropping the car at tthe Marseilles airport?
www.voyages-sncf.com for fares and schedules and if you book far enough in advance you can get discounted but train-specific tickets that cannot be changed nor refunded - full fare tickets should always be available in Paris.
If you want to stay in a hotel your first night then pick up the car the next day, after exploring Strasbourg sans car and a day of car rental there is a phalanx of hotels right opposite the Strasbourg main train station bereavement airline fares - I stayed in the bargain but good IBIS ( www.ibishotels.com - part of the Accor group (www, accorhotels.com ).
