Stopping for lunch in France, drive from Italy.

[fredt]

I will be driving from Courmayeur to London in a couple of weeks time. I will time it so we have plenty of time, 2 hours or so, for a good leg stretcher and a nice lunch.

Ideally somewhere between Troyes and Reims. We have two boys 4 and 6 so somewhere with a playground or something fun for them would be great, and also where me and the Mrs can get some decent scoff.

Anyone with a good idea?

Thanks!
