The truth is, resorts want you to ski or ride more often. Because you are willing to commit in advance to specific days, and know that you can't cancel your booking once it is done with, Liftopia makes it safe for their resort partners to offer exclusive deals through their site. This way resorts can try to get more folks out on the slopes, without hurting their on-mountain prices. The term in the industry is "incremental purchases", which essentially means that with better deals for specific days, you will want to ski or ride more often than you would otherwise.
