Breckenridge? You gotta be kiddin' me. No quibbles with Jackson Hole, Whistler, the eastern resorts you mention. The people who flooded in the votes are interested in glade skiing, steeps, and what the kids would call, "vibes." Driving there in a Mercedes SUV and skiing alongside yuppie families isn't their thing.
With all due respect, I've seen your lists of vacation spots, and you prefer the wildly-attended places, some of which are, frankly, overrated. I would be tempted to say "many."
