We're spending four days over Easter in the Tyrol and decided to cut costs slightly by driving each way. And we decided to do the drive overnight so the kids slept through most of it. The route planners reckon it's about 12 hours including the Eurotunnel. Are we insane? And more important, will we be able to buy fuel somewhere on the French/German border in the middle of the night?! I know lots of French petrol stations used only to take the Carte Bleu. Is this still the case?
