I think they put it at such a high price specifically to keep it from selling out. The area has a limited capacity and the viewing areas even less. I'm pretty sure that the event is just WWoHP, so when the show ends, there really isn't anywhere for anyone to go. Keeping the attendance (relatively) low keeps the crowds from overwhelming the land and making it uncomfortably crowded. And, yeah, it would sell out in a heartbeat at $75, but if only half as many people buy tickets at nearly three times the price, the company is still making more money and the guests that do attend have a better overall experience.
