I'm looking for some advice on planning a trip to the Normandy and Loire Valley areas. We'll be a group of 6 adults, ranging from 50's to late 70's. We'll be going in late June/early July 2018.
I have 12 days to work with, give or take - I haven't booked flights yet so some flexibility remains. We'll be flying into and out of Paris (with a Seine river cruise and a couple of extra days in Paris on the tail end).
The plan is to rent a van (or two midsize cars) in Paris and wander a bit. A van large enough for 6 with luggage might be unwieldy in smaller towns, so am leaning toward two cars, which will be a consideration in choosing a home base.
Have done the 1-2 nights per location thing elsewhere before in other parts of Europe and found it a little hectic, so am trying to limit the moving around as much as possible, meaning 2 (maybe 3) apartments or house rentals that are good jumping off points for the sights in each region.
How would you structure your trip to the area with ~12 days to spend?
Suggestions and comments welcome.
