I really need help squashing a nagging question in my mind. I am to fly into CDG and make my way to my lodgings in Monthodon. I have seen many people suggest taking the TGV to Tours from CDG and renting a car from saint-pierre-des-corps. Why is this better than getting a car from the airport and driving to the area? I can't price my ticket yet because I am leaving in mid September and they aren't for sale yet. I told the place where I was staying that I planned to take the train then rent a car in Tours and they said that I should just rent it at the airport and drive there. So I am looking for more direction....thanks.
