Hi everyone, and thanks for reading.
My husband, in-laws and I will be arriving at CDG. Our itinerary is to spend several nights by the D-Day beaches, then drive into Belgium to do the Battle of the Bulge sites. From what I've read, it seems best to rent a car in Caen rather than at the airport and maneuvering city traffic after an overnight flight.
After hours and hours of googling, I have come up empty-handed on recommendations for a car service/transfer. If it was just my husband and me we'd definitely do the train but I think it will be problematic for his parents.
