I don't think they would lose any money, maybe just not make as much profits from what it cost them. Anyway, ive never even been there, and the reason I'm going this winter is for the park mostly (and everything else of course). So even if the parkpass is cheap, since im buying a season pass (or day pass) they still make huge money. They also make money on everything else (hotels, food, etc) so yes, they do make it for advertising also
