I will have a 17 hour layover at CDG on a Wednesday night in September. I haven't been to Paris in 15 years and my husband has never been. We would love to take the train into the city, grab a late dinner, walk around and see some sights at night, sleep for a couple hours in a modest but clean hotel, then grab breakfast at a cafe, maybe a little more walking and then back to the airport for a 1:40PM flight.
What area of Paris do you think we should stay in? Thanks for the help!
