We're staying several nights in Paris before going to the Loire Valley. We want to rent a car for that portion of our trip and then return it at the CDG airport before spending a night near the airport and then flying back. We are 4 adults. We plan to go from the Loire Valley to Mont St. Michel and then to the CDG airport.
Should we
(1) Rent at the CDG airport since we can easily get there from Paris and then drive on to Amboise? I'm concerned about driving through Paris to get there; however, my son is an excellent driver, and he will be driving. But he's never driven in Europe.
OR (2) Take a train to Tours and then pick up the rental car. We would incur the train tix for 4 adults to get there and likely an additional charge for returning the car to a different location.
Also, if anyone has any helpful tips on doing this, please share.
