just came back from park city where we skied all 3 resorts. Our group consisted of 7 intermediate skiers.
Deer Valley - we went here 2 days as we were trying to avoid snowboarder. The first day was sunny and it didn't snow for over a week so the trails were well groomed (probably too well groomed for me). The second trip it was snowing (not much but enough to make the experience much better). You definitely want to check out the area with the Gondola which is behind the St. Regis, it is the best kept secret to avoid the crowds.
Park City Mountain Resort - we did this on the last day and this place is huge. certain areas had over 6" of newer snow. Our group wasn't used to skiing in this type of powder as we are from back east, but it was great. They have a great variety of terrain as well.
The Canyons - they received about 7 inches of new snow the night before we came, All I can say is WOW. I like the terrain as well as homes that are nestled inside the resort...pretty cool. My sister in law took lessons here as they were the only ones who offered full day beginner classes.
Overall, the group was split between the PCMR and the Canyons. While we thought we would like deer valley the best (due to no boarders) that was not the case. We did like the service at deer valley where they have guest services reps at the top of the lifts to help direct you to a great trail. I definitely change my opinion of boarders as this trip. I think my distain towards them was two fold. First is the fact that back east you hear the boarder coming from at least 100' away. This is definitely not the case out here where you actually have snow! Secondly, I determined that the boarders back here just don't know how to board properly.
While we wanted to head out to Alta, we couldn't as we spent a night at the Chicago midway airport that took away from our skiing.
As nice as the resorts were, we still prefer Snowmass. But it is close....no trying to figure out were to go on next years trip.
