I am trying not to drift too much into the realms of fantasy...but here goes.
1500-2000m vertical-so a long season with a glacier at the top and tree skiing at the bottom. Minimum mid December to end of April.
Fast chair lifts. Bubble lifts only where necessary. No cable cars (trams as I think you call them in North America). No T bars!
A good nursery area at the bottom of the mountain and some good green/blue runs for beginners from the top down so they can enjoy the whole skiing experience.
Wide speedy ego boosting red runs for carving practice
Wide gentle off piste skiing both above and below the tree line-all in bounds and patrolled.
Some more challenging stuff-on an off piste above and below the tree line.
At least 200km pistes linking at least 2 villages/resorts without the need for a bus.
"Gladed" ski areas North American style (we don't get then deliberately created in the Alps-which is a shame).
A characterful old mountain village at the bottom with lots of cosy accommodation, great restaurants and good service-all ski in/ski out, or as near as makes no difference.
Great on mountain eateries- nearly all table service. I am thinking I need to get the Italians in. Also the occasional mountain hut serving the best hot chocolate/vin chaud in the world.
Great english speaking ski schools.
Something for non skiers to to-good hiking and cross country routes, some dog sledding.
Pedestrian access via the lifts to a god chunk of the hill so that the non skiers can meet me at lunchtime!
A ski demo hut with every brand of ski you could possibly want to try out.
A snow fall of minimum 11m per year.
Don't ask much do I!
