The company will restrict access by halting ticket sales to Disneyland once it reaches capacity, which is estimated at 75,000 to 80,000 people. During those peak times, people who already have admission tickets normally will be allowed to enter, but no new tickets will be sold until enough people leave the park. Visitors are encouraged to go next door to California Adventure as an alternative.

Disneyland was so crowded Dec. 10 that it closed the gates to everyone temporarily, something that rarely happens, Storbeck said. Disney has implemented plans since then to avoid another closure, if possible, and to augment its usual crowd-control measures.
