You are really pushing it. Land at 12:30pm, by the time you get off the plane and get your luggage it could be almost 1pm, then rental car is 15 minutes, but you could be stuck in line for an extra 15 minutes or even more, sometimes the lines are long. 15 minutes to change, 45 minutes to Park City. At the Canyons you likely have to take the parking tram from lot to mtn, at PC finding a parking spot could be difficult but last week we parked only 100yds from the lower lift.
In line by 2pm would be awful lucky, 2:30pm is more like it. If you are staying in PC it's definitely worth it, cause your already there and its' free. Not worth it, except for free Quick Start, not sure if that covers PCMR night skiing. I did the QuickStart last week, we landed at 10:30 and were in the lift line at 1pm. But it could be 12:30pm moving a little faster.
