Has anyone picked up a rental car at Gare Montparnasse? We are driving to Mont St. Michel. We are picking up a car on Sunday morning, I've checked and we can pick up our car at Gare Montparnasse on that day and time. Taking the train to Rouen will not work because I can't find a rental place that is open on Sunday.
How hard will it be for us to get out of Paris? I have driven in Italy, not in a city, but in Tuscany and the Amalfi coast. On the map the route looks pretty straight forward, but I would love to hear from someone who has done this before. We can also pick up the car at Orly or CDG, but Gare Montparnasse is not far from where we are staying.
