Money quote: "Rather than ordering Tickets through the TM System, customers purchased Tickets to the Attractions in person at the Facility Box Office to avoid the prohibitive Convenience Charge. The effect on the Debtor of the increase in the Convenience Charge has resulted in a reduction in the Royalties that it receives due to a decrease in the number of Tickets sold through the TM System."
Apparently they were selling tickets at not quite break even, and depending on their cut of ticket master fees to turn a profit.
Aligns with my experience trying to avoid fees by buying in person. Usually there ends up being a "box office window" fee.
