I am planning a family Christmas ski trip. Half of us are intermediate to expert skiers and the other half are beginners. We thought about The Canyons in Park City, but one of the avid skiers in the group said that may not be the best place for snow in late December, and suggested Heavenly in Lake Tahoe. Can anyone tell me where in the USA will most likely get the best snow in late December? We could also go to Colorado if skiing there would be better. Any suggestions would be appreciated.
