France driving trip - how to save on expenses?
I'm planning a driving trip to France in August: starting from Paris - to Nantes - La Rochelle - Bordeaux - Toulouse - Limoges - Orleans - and it ends in Paris again.
The itinerary is like here http://www.voyajo.com/viewTrip.aspx?trip=106745 but without visiting Spain and Andorra. I'll just cut from Bordeaux to Toulouse.
How long can the trip take? Minimum length - if I stop only for staying the nights?
It's a high season, you know, so I need advises how to save on expenses: cheap gas stations, cheap but good restaurants, clean affordable hotels/apartments and so on. Buy the way, which car rental company should I choose?
The points of interest I'll leave for the next stage of planning
Thanks in advance!
