We're planning to drive from Calais to the French Alps next summer with kids aged 11 and 8. We're looking at possible stopover ideas, and considering taking them to Paris, as they've never been. So, the question is - would one to two days (two to three nights) be worth it? Is there somewhere nice and convenient to stay where we could park easily and avoid driving right into Paris, but could easily get into the city on public transport for the day? Would need to be on the Eastern side of Paris for convenience. Or - is this a foolish idea?
