As of March 2026, you must confirm that you have a valid theme park reservation before heading to Disneyland Resort in California, as they are still strictly required for all guests. Unlike Walt Disney World in Florida, which removed the requirement for most date-based tickets, Disneyland continues to use the system to manage its higher density and local "Magic Key" (Annual Pass) population. In 2026, you don't necessarily need to "re-confirm" a reservation you've already made, but you should verify it appears in your "Future Plans" section of the Disneyland App. If you purchased a ticket directly from the Disney website, the reservation was likely made at the time of purchase. However, if you bought through a third party or are using a Magic Key, you must manually go into the system to select your date and starting park. In 2026, reservations can be made up to 240 days in advance, and failing to secure one will result in being turned away at the gate, even with a valid ticket in hand.
