I care about terrain -- that's it. The Canyons does NOT have it. If they call it blue, it means you don't have to pole. If it is green, count on poling most of the run. If it is black, it will be short and dump into a half-mile long runout.
Seriously, avoid this place. They have a few good runs mixed into the ridiculous layout, but those are not worth the price of the lift ticket and all of the other terrible runs you have to endure. This is the worst option in Park City. You will have a much better day if you drive an hour to Snowbasin or around to the Cottonwood Canyons.
