I drove down to Meribel last feb and it cost £160 return. In two mnds, if you do alot of motorway driving the autorouts were great, but for occasional use they are expensive, that trip just about covers the road tax in the UK, oh and threre's the fuel on top of that. But it was cheaper, three up, split the fuel costs, ferry crossing and toll roads than getting a flight.
We did a bit of a Topgear run, another friend left at a similar time drove to Manchester Airport, waiting for his flight, flight time and transfere time, we drove to dover and ferry over to calais and down to Meribel, three of use split the driving non stop and beat the flight by 4 hours, he did have a 2 hour delay at manchester, so it would have been close if he was on time.
On the return when we left it was snowing heavily, but we drve on, no prob's, guess what his flight was delayed again, ha ha and we beat them home!!!!!!!!!!!!!
Landrover's Rule - oh i was in my gaylander that i had at the time, obiously wised up and got the full fat rangie.
