Elk is the way to go if you want anything close to VT riding, but they don't have high speed quads and the lift lines get pretty long on the weekends . I would say go to Jack Frost, it's not just the mountain, but the whole Lake Harmony / Big Bass area has more to do and probably better for a vacation since it is more of a resort area then the others mentioned. don't go to Spring Mountain, not especially if you are talking about "glades" or steeps....
I love Blue though...
