It still kind of kills me that you are finally giving Utah a shot and planning on sticking only to Park City. Since I know you are used to Colorado, I'm not sure Park City will give you a whole lot outside of what you are used to in Colorado with its expensive tickets, food, lodging, and Colorado comparable snow. Yes, it is a VERY cool ski town. However, if you are going to Utah for Utah runs and Utah snow, you just aren't really going to get it there. Those are found up at the Cottonwood resorts mostly. Therefore, if I can at least plead anything with you, it would be to use that last day of skiing as a trek over to Snowbird (Alta is no-boarders). Truthfully, I'm not sure how you can ski Utah without skiing Snowbird for a day. Plus, you'd get your first tram experience too. There is none of those in Colorado.
The group decided Park City. I'm honestly fine with anywhere. Just fun to get away and not have to worry about keeping 3 kids alive for a few days
I think the last day we might trek over to one of the Cottonwood resorts. If the weather is bad, worst case scenario, we decide if we want to do Park City again or Deer Valley and make the boarder ski ha!
