Have mapped out this- Paris to Roen via train, get rental car and head to Normandy (D-day beaches) then on to Amboise (Chenonceaux, Chambord, Cheverny) then drive to Auvers-sur Oise. Will do this in 4 days. On 5th day need to get to CDG airport for a 12:30pm flight. Best way to get to CDG (can't get train info from Pontoise) or other ideas how to rework this loop? Thanks!
Get your train info from the German rail site, which says there are frequent trains and that the trip takes less than 2 hours. Or you could just keep the car another day and return it at the airport.
Funny that I can get train info/schedules from a German rail site and not raileurope! Thanks for the tip! No desire to drive anywhere near Paris! YIKES!!!
Driving around Paris is no big deal. it's just freeway. It would be much easier for dropping your car at CDG.
