Hit up Les Deux Alpes, they have an awesome park. AND its linked to La Grave, probably the best lift served backcountry on earth.
It has about 2000m of vertical, no trails, just a mountain. Pick a route and ski it. You can always find powder there.
The bottom can sometimes lack snow, and if you don't know where you're going, you may have to walk a bit. Try get a local guide, he'll keep you out of crevasses (sp?) and away from 400ft cliffs, but he'll know all the sickest spots.
