I used to regularly do Meribel from Calais in 8 hrs in the Van.
I got so fed up with the hassle and time wasting at airports, it was as quick to drive down there as it was to:
drive to airport, park, get bus, check in, security, wait, go to gate, wait, board plane, wait, flight, land, wait, leave plane, wait for baggage, exit airport, check in with hire car company, sort car, drive for another 2 hours, reach destination.
If there is more than one person and decent amount of Luggage the balance sways even further towards just driving IME 8)
Mates, music, roadtrip on decent roads, Lift assisted bike stuff at the end of it – whats not to like ?
