Which ski resort in Utah is better for beginning skiers and snowboarders-Park City or the Canyons?

I am planning a family trip to Utah in December. We need to stay near/in Park City. Some kids (and adults) want to ski and some want to snowboard but most of them have never done either. Between The Canyons and Park City, which would be better all around for beginners (Deer Valley is out because it doesn't allow snowboarding)?
