High speed lifts, tons of snow-making
Boring terrain, misleading vertical and snowfall stats
Park City is a hot-spot for vacationers because of the atmosphere, but the skiing is frankly lacking compared to other Utah options. While it is nice to have high-speed lifts taking you almost anywhere you want to go, the terrain they take you to is just not incredible. Beginners are stuck at the bottom of the mountain, unless they want to brave the crowds on Homerun, which is the green top-to-bottom funnel that EVERYONE ends up on. It gets really crowded, so I wouldn't take my beginner down it.
The snowfall is measured at the peak of the mountain, where only experts get to, and that spot isn't even open until they get a lot of snow. The base of the mountain gets way, way less than advertised. However, they do make a ton of snow, so that is good.
The advertised vertical is also only available to experts, and the way the lift system is arranged, most runs only give you 1000 to 1300 feet or so of vertical. In other words, the runs are not very long. This is an issue with all three of the park city area resorts -- they are spread over multiple peaks with no one peak providing very long runs.
I think this place is fairly over-priced for what you get. Make the 50-minute drive to the Cottonwood Canyons and enjoy the better snow and better terrain at Brighton, Solitude, Alta, or Snowbird.
