To enter Disneyland Resort in 2026, every guest aged 3 and older must have two essential items: a valid theme park admission ticket (or Magic Key pass) and a confirmed theme park reservation for the same park on the same date. Because the reservation system is used to manage daily capacity, having a ticket alone does not guarantee entry. Reservations are made via the Disneyland app or website on a rolling basis, often up to 120 days in advance. Additionally, guests are expected to adhere to the resort's Code of Conduct, which emphasizes treating others with respect and kindness. Security screenings are mandatory for all visitors, involving bag checks and metal detectors. It is also a grounded peer recommendation to download the Disneyland App before arrival, as it is required for mobile food ordering, checking wait times, and managing digital tickets. While health-related mandates have largely subsided by 2026, Disney still reserves the right to implement safety measures or capacity limits as operational needs change, making "checking the calendar" the most important pre-trip step.
