We usually have the month of June to travel, and this year have tickets in/out of Paris June 3rd/June 30th. We've recently spent 10 days in Paris, so we won't be going into the city. We're renting a car. Originally we'd planned to make a wiggly circle to see the rest of France. We usually stay in most places 1 or 2 nights, with an occasional 3rd night. Though longer apartment stays are popular, we prefer not having a home base to go back to for multiple nights. Mainly we like to be in new places with ambience in the longer summer evenings, walk around, sit in squares. We're interested in history more than fine art.
So, our (happy) situation - after looking more closely at the RS planning map, we realize that 27 nights will not be enough and we've decided to see 1/2 of France this summer and come back to France again in June 2017 to see the rest.
We're thinking in this case of taking the ferry to Jersey/Guernsey Islands for a few days this year, since we'll have more time flexibility, and next year of taking a similar amount of time to explore the Basque area of Spain.
My question is, where are the logical geographical breaks? I'm looking at the planning map and the center area of France seems to have fewer featured sights/sites. What are your opinions of best ways to take in France in 2 equal chunks?
Merci beaucoup!
