Hello, we are planning to visit Normandy after several days in Paris. My preference would be to take a train and rent a car at Caen or another location in Normandy. Howevever, I cannot drive a manual car and need an automatic transmission. I have read on TA that obtaining an automatic in Normandy is much less likely than in Paris, so I am planning to rent in Paris, then drive to Giveny and onto Bayeux. We'll be staying in the 5th or 6th. To date, I have managed to reserve an automatic with Europcar to pick up at Gare Du Nord.
(1) Since I understand that an obtaining an automatic is not "guaranteed" (despite the reservation), is there a location better than Gare Du Nord where I could more likely expect to get an automatic that makes sense given my travel plans? CDG might have more cars, but it also seems out of the way. Would CDG nonetheless be preferable?
(2) I have reserved a "Renault scenic auto" (or something similar). Does that seem large enough for an adult and two teens and luggage?
(3) We are tentatively planning to eventualy drop off the car at Deauville and fly from the airport there via Cityjet to London, as opposed to driving back to Paris and then taking the Eurostar. At 71 euros per person one-way to London, Cityjet seemed to be the more efficient alternative. Does this make sense?
Thanks much for your help.
