Its good fun flying into Courchevel I fltplanned to Courchevel just before xmas, couldn't get in there due wx and diverted to a v.busy Chambery. Left the a/c there and it's about 1h30 to Courchevel 2hrs to Val d'isere. Not a bad journey at all but taxis v. expensive (€250+!!)
One tip, you may have trouble getting your ifr fltplan accepted with a route to Chambery due the high traffic density at weekends there (ski holiday changeover days). Trick i pulled was flt planned to Courchevel even though I knew there was an 80% chance I wouldn't get in there and got it accepted but diverted to Chambery with Geneva controller.
