My husband and I will be in Paris for 12 days in October. At the end of our trip, we have 3 days to fill. We thought we'd go to the Normandy area. Thinking about taking the train up to a starting point, renting a car and touring around. However, I need suggestions regarding making the most of our time. Should we plan on staying in the same location? Or stay in 2 different locations? We will end at CDG for the last night. Is Caen a good base for going to the Normandy beaches, Mont St Michel, Bayeux etc. Has anyone driven this area and have suggestions regarding travel time between locations etc. Would Giverny be a good start from Paris? I'm finding it much easier to plan our time in Paris then these last few days. Any advice is appreciated.
