I will be traveling in France for 3 weeks in October/November. I'm planning my trip such that I will have three base "hubs". I'm having a hard time deciding on my third hub where I'll be for about 5 days - I'm waffling between Provence and the French Basque area. I'm leaning toward Provence (Avignon or Aix-en-Provence) for its more direct access back to Paris (as my return flight is out of there). I've also had a hard time deciding what a good base would be in the French Basque.
Also, as I'm traveling near the off season, I'm curious if I will have problems if I travel without reservations. I've considered only reserving for a night or two to leave myself open to staying in smaller towns.
Thanks for any help.
