We’re driving from the tunnel to Lucerne, Switzerland in the summer and need somewhere to stop off overnight. I want to get about 4 of 5 hours of driving done on the first day which takes us to the area around Nancy & Metz. Anyone been to either of these cities or anywhere around there that they’d recommend? Ideally somewhere we can have a wonder around for a few hours in the late afternoon, get some food and a few hours exploring the next morning before we set off again.
