We are staying in Paris for several days, then traveling to Litteau on a Tuesday and returning to fly out of CDG on Friday of that same week. I thought about taking a train to Caen and renting a car there, but with 4 adults traveling, it's a better option to drive from Paris. I want to avoid the city traffic as much as possible - is it best to rent a car at CDG and return it there, or rent somewhere else and return to CDG when we fly out?
TIA.
