I'm going to France for a week in August with DH, DS (8) and DD(5). I want to go into Paris for the day while we're there. We'll have our own car but the thought of driving in Paris is awful and I know you need passes etc now. I'm aware that there's park and rides but does anyone have any advice about the best way to get in to the centre? We'd be coming from the east with Troyes being the nearest city. I'm wondering if the train might be the best option? Thanks
