Replying to Going to Utah...what to visit snow wise

Next December I am going to Utah.....

I am spending like a 8 night 9 day trip out there next December.

Little early I know.

Probably staying in Sandy or Midvale since lodging is leaps and bounds cheaper. But I was wondering what should I visit out there?

Alta / Snowbird looks like a given from what most people say. Also Park City seems to be popular for its terrain park.

But I want YOUR advice here.

You have 7 days of skiing in SL, UT. Tackling the pow and the parks....

What would you do?
