For small trips through France you'll probably get cheaper without this pass. When I'm in vacation I do 2-3 days in a city than move on. If I exclude Milano-Lyon, I don't think I ever payed more than 40€ through France and I did Lyon, Paris, Rennes, Brest, Nantes, Bordeaux and a few other cities. The only thing is that I book way in advance.
When I returned from Germany, two months ago, the lady next to me was amazed that I payed Munchen-Verona 37€ while she did 100+.
