I know the car vs. train question has been addressed, but if more experienced people don't mind taking a look at the specifics of our trip, I would love some advice. We are planning for a trip early next summer (mid-May 2019 to mid-June 2019). We will have two adults, a 16-year-old, and a 10-year-old (all interested in history of all periods, especially of both World Wars). General shape of itinerary so far:
Fly into Paris, spend 5 nights
Travel to Mont St. Michel, spend one night there
Travel to Normandy, spend two or three nights in Caen or Bayeaux
Travel to Ypres area of Belgium, visit WW I sites, spend one night there
Travel to Amsterdam (or vicinity), spend four nights
Travel to mid-Rhine area (St. Goar? Boppard?), spend two or three nights
Travel to Munich (would love to stop and see Nordlingen on the way, if we have a car, not sure if we can with a train), spend 5 nights in Munich
Travel to Murren, Switzerland, spend two or three nights
Travel back to Paris to fly home -- maybe stopping one or two nights somewhere near Dijon, not sure about this part yet
I had been planning to lease a car in France, on the day we leave Paris, since it seems a leased car will be less expensive than buying four train tickets for each step of the trip. I had also thought we might have more interesting lodging options with a car to get to Air bnb or Guest to Guest home exchange possibilities. However, I am starting to think train travel will be less stressful. With the above proposed itinerary (which is not set in stone, of course) would we be able to see the World War II sites in Normandy and one or two World War I sites near Ypres while traveling by train? I love the idea of being able to explore some of the countryside areas with a car, but am now doubting if that flexibility will be worth it. I do most of our family driving, and generally don't mind driving at all. I drive in Chicago regularly, have driven in Manhattan, and have driven through mountains in Colorado and California. So I am not particularly worried about driving in Europe, but I know it will be more stressful than driving at home. I am mostly thinking about maximizing our money and time. Any advice on transportation related to those priorities (time and money) would be appreciated.
