Mickey Mouse Lets You Ride "for Free" at Disney World

Walt Disney World Theme Parks offer visitors a wide variety of ticket choices. The one thing these tickets options have in common is that they entail a fixed entrance fee and allow customers to take as many rides as they want at no additional charge. For instance, by purchasing a 1- day ticket for about $105, a customer gains unlimited access to the park of her choice for one day.

Wouldn't Disney earn higher profits if it charged visitors, say $10.50 each time they went on a ride? Explain your answer.
