So hubby and I will be arriving in Paris on Sept 27, which is going to be 'car-free' day. We will most likely take public transport to our airbnb, which is in the 15th arr...but right on the border with the 7th (about 15 min walk to Eiffel). Arriving probably early afternoon depending on how long it takes us to get from the airport (plane lands about 9:40).
So...my question...if you were in Paris on car free day...what would you do? Dance down the middle of Champs Elysee? Run circles around the Arc? Is there somewhere that could be really interesting to walk that would be made even more awesome by lack of cars? This will be our 3rd time in Paris (staying 3 nights), and we've seen most of the 'big' stuff, and I have thoughts for our other 2 days, but this seems like a golden opportunity to maybe roam a normally busy car-filled area (I do realize that there will be some traffic from buses and locals and taxis...).
