this is how we do it:
– 10pm ish ferry – drive until about Reims, then stop in an Aire.
– Sleep in pop-up tents (cheap decathlon 2 second jobs).
– Drive for about an hour then stop for a cuppa and a pain au chocolat in one of the aire restaurants (l’arche etc.).
– Keep on plugging on, stop in the Carrefour at Dijon (not too far off the autoroute) for lunch (pizza’s from their Traiteur are great) and to buy any supplies you want to stock up on (much cheaper than resort town supermarkets).
– Arrive in resort mid afternoon (bit later if you are heading further south – les arcs etc.)
On the way back, leave mid morning for an evening ferry, stopping again at Dijon for lunch. Alternatively, leave mid afternoon, stop at dijon (or chambery) for dinner; kip in an aire up near lille and catch an early ferry.
Two drivers are a bonus, but if we are stopping for a sleep, then I have no problem doing it all myself. When we went down to Les Arcs in Jan, we did it all in one push – caught a 10pm ferry and were in town checking into our apartment at midday the next day.
Route: Calais | Reims | Troyes | …
then either Bourg-en-Bress | Geneva | wherever…
or Lyon | Chambery | wherever…
Unless you are going to italy, don’t follow your satnav through the mont-blanc tunnel. In winter, then col’s to get back over are often shut, and the tunnel costs quite a lot anyway!
