If a warm front hits, head to Park City Mountain Resort a little before 11 a.m. to be first in line for the recently built Alpine Coaster, a 6,000-foot-long track that whips you through sharp bends on a gravity-propelled cart. Next, check out the resort’s off-site Gorgoza Park, where you can race kids (yours or other people’s) on inflatable tubes. The park’s seven tubing lanes are lit so you can careen straight through to dinnertime. Finally, reserve a spot inside the Canyons’ Viking Yurt, a mid-mountain dining hut reachable only by Cat-powered sleigh. A five-course meal, with complimentary spiced-berry glogg, coffee, live piano music, and—if you can still walk—a guided, pre-supper snowshoe trek, awaits.
