We are a family of 3 looking to see some of Brittany & Normandy this September. How is it driving in a rented car along the coast? My husband and I prefer to travel by train so we can relax, but it seems like more can be seen in this area if you have a car. The towns on our list include Dinard, Dinan, Mont Saint-Michel, and Honfleur. Any comments, thoughts or advice about train travel vs. car travel would be appreciated. We are not as concerned about cost as we are about relaxing and being able to enjoy the scenery.
