Visiting very long long relatives in the summer in Charleville Mezieres, in the Ardennes/Champagne region.
The way the dates work out, we'll have to try to squeeze it into a weekend, as DS will still be at school.
We live near Heathrow so would love to fly there, but think the nearst airport is Paris.
DH has never driven on the right hand side of the road. I'd be happy enough to hire a car when we're there, or even take our own car there, as I imagine it's a fairly sleepy kind of place, but I do worry about the motorways to get across France, and also worry about driving out of Paris, if we got a flight to Paris.
Can't check train fares for July yet, but the return train fare, in March (i looked just to get a rough estimate of cost and journey time) would be nearly £300 for DH, DS and myself 
Has anyone done this journey before or have some tips about how the hell to get there, reasonably cheaply, in one piece, and preferably with marriage still intact?
