My office in NYC is vacant --very strange--but yes i have been twice. Once hard snow and once bottomless powder. You don't have to be better than intermediate --they have all levels. I thought it was good--but you could be with a group of 6 or 7--so while you'll ski your brains out--there can be waiting for slower members--much depends on the instructor and the conditions--also--being the best skier in your particular group is not ideal. Having said that--if you like a big mountain that's ultra steep--there's nothing like Jackson Hole. You should go.
