As to the overnight stay - use the 'mappy website'
Mappy - plans, itinéraires, guide d'adresses en Europe to get the route [about 12.5 hrs driving time], and use the route map to find hotels - by zooming in a bit on where you think you can get to, and then use the hotel search facility on the left of the page. If you hit the 'tous hotels' facility it shows where plenty of hotels are in the area.
Good luck.
