Thanks for your reply.
I agree about how smaller kids do in deep snow. However, in about a foot of snow, mine do just fine.
But if you are saying that Park City is better than the Cottonwoods because the Cottonwoods might get to much snow, that seems a bit strange. In that case, why not go to Colorado? Quicker, cheaper flights.
As far as lodging, you are certainly correct, there is more choice and better pricing in Park City.
But the fact that PC has more dining and entertainment options is not relevant to this thread: after all the OP stated he will cook in his condo and hang out there, so “entertainment’ doesn't matter.
As far as the size of the resorts, for 4 or 5 days, he will hardly be bored in the Cottonwoods. So again, the fact that PCMR is larger is not very relevant to the decisions in this case.
Then there is the terrain. Brighton and Solitude certainly have plenty of intermediate terrain, and others have said Alta does to.
You stated that when Alta has a powder day, so does Park City. That does not seem to be correct: According to bestsnow the chance of a 6” powder day is 20% at Alta but only 12% at PCMR at around 9000’ for both resorts.
So actually that amounts to PCMR getting only 60% of the Powder days Alta does.(at 9000’).
