Has anyone given any thought to Big Sky in Montana? Lone Peak has some of the sickest terrain outside of Jackson Hole (which would also be awesome and much easier for people to get to from abroad)It has great side and back country and very cold, very dry snow and usually clear and cold sunny weather. Gallatin Field in Bozeman/Belgrade is an easy hub for airfare and cheap accomodations can be had in Bozemen if you want to keep the cost of on hill lodging down and from Bozement it`s just an hour`s drive. Personally with logistics hurdles, Wolf Creek seems like a lot of work even though the snow and terrain is great. Not knocking the idea, but just tossing some other ideas out there...
