I understand that on Sunday of September 16, from 11 a. m to 6 p.m, all the center of Paris will be without any cars, buses or any kind of vehicles using gasoline or diesel. The only way to move will be, using the metro or walking. All this paralysis of cars and transportation is because September 16 ,2018 is the celebration of "Journee Sans Voiture."
With a departure time of 11:53 on that Sunday, what will be the best way for the two of us to get from our apartment to the station (with two rolling carry-ons)? And what time should we plan to leave for the train station?
