Disney tickets clearly state that they are "nontransferable" and must be used by the same person on all of the days, so the theme park has trained its gates workers to be on the lookout for visitors using the rented passes.
In some cases, the agency will white out the tourist's name or provide the tourist with a card detailing how the pass was used by other visitors on previous days in case Disneyland employees question them.
Beth Holderness bought tickets at a strip mall for $80, but was caught at the gates of the Happiest Place on Earth when she was asked what time she had been there the day before. Holderness, of Arvada, Colo., replied that it was her first day and Disneyland confiscated her passes.
"I feel like a criminal, but I thought I bought legitimate tickets," she told the Register.
Craig Neil, owner of Anaheim Tickets on a side street near Disneyland, said less than 2 percent of customers have had problems.
Visitors can get refunds or new tickets, he said.
"They do check some of the tickets, but they don't check all of them," Neil said about Disney ticket takers. "Otherwise, we would not be able to stay in business."
Neil said his workers tell buyers how to avoid getting caught, handing them a business card listing when tickets were purchased, where and when they were last used. He said a family of four can save about $100.
