Will be visiting France with family in May. We plan to rent a car in Paris, drive to Pontorson and stay for two nights so we can have a full day in Mont Saint Michel. The problem is that for our itinerary to work, we need to drive to Pontorson the day before Ascension day. I hear this is a day with heavy traffic to get out of Paris. We still wanted to do some sightseeing in the morning and start our drive after lunch. Does anyone know how bad traffic should be? What would be the expected time to get to Portonson from Paris if leaving around 1 PM? Would it be better to get the train to Rennes and drive from there?
I get a bit anxious with the idea of renting a car in Rennes. We have two small kids and will need two car seats, so I always wonder if we'll have issues with that in a smaller city. Also there's the extra expanse of the train for 4 people.
Thank you!
