Terrain, snowfall, on slope ammenities
This place is like Deer Valley and Park City's hotter, smarter, kinkyer sister. It has everything that they do and more, MINUS the price. More primarily being steep terrain, vertical, challenge, snowfall, etc. Since it is a Sun Valley/Earl Holding owned resort, they don't skimp on the luxury or the ammenities, so there is your Deer Park experience right there. But at the same time, they have some rediculous steeps that occupy an actual mountain, rather than a steep foothill like most of Deer Valley, so you get that awesome terrain variety like you would at Alta and Snowbird. It's the best of both of those worlds because it doesn't get the crowds that Alta and Snowbird do, but it still has the on slope dining and luxury that Park City and Deer Valley have. Still, the olympics really put this place on the map, and it is starting to get awfully crowded, especially on weekends.
Still, if you are looking for some fun and a good challenge for a reasonable price, this is gonna be your place.
