The Canyons is exactly 5 miles closer to the airport than DV.(drove it daily for 15 years).
U can see if the Utah Ski and Golf outlet at the airport sells passes to DV I'm sure they still do.
as for the chair lift out of the parking at the Canyons, once you off load, you still have to walk to the gondola for another 10 min ride.
So now you have ridin 2 lifts and still have touch the skis to the snow.
At DV you can ride the shuttle from parking lots( mordern paved,organized,patroled) Stop st the ticket office, walk 25 feet and your in the maze for Carpenter Express, you'll be skiing in less than 8 minutes.
If you cant get to DV before noon, once you do, head up/over to Bald Mtn and hit the groomers i spoke of in an earler post. This time of day, people will be drifting towards Northside, the busiest lift at DV, due to the 8 groomed,low level terrain.
Sultan And Mayflower are triples, that gives you plenty of rest on the way up.
If your going to do lunch, have it at Snow Park, less crowds go there, cause it's the base lodge. The same quality food is served there, As is the Exec Chef. Also there are snack huts at the top of Flagstaff and Bald Mtns offers soups, the famed Deer Valley Turkey Chili, pastries. As well as coffee, hot coca, soft drinks. Try the carrot cake and Oat meal Rasin Cookies

At the Canyons, once your on the upper mtn, there is only one place to eat, and it gets crowded early, and stays that way all day.
If you want to eat elses where there, you either have to go over to the older part of the resor(still the better skiing) or ride the gondola down to the base for lunch.
