Alta or Bird for snow.
Brighton is stupid. The only advantage is less crowds. besides that, the park is beat as hell, and there's nothing about the terrain that makes it better, unless you like traversing a quarter mile, dropping one cliff, and traversing out. I mean, you can do that all day, but why would you?
PC or Canyons for park. I know a lot of people getting a canyons pass this season, I think it's going to be a really great time.
