For a visit in 2026, guests can make Disneyland theme park reservations up to 240 days in advance on a rolling basis. This applies to standard theme park tickets and vacation packages. It is highly recommended to book as soon as your window opens, as popular dates like the 70th Anniversary celebration (which runs through August 9, 2026) and holiday periods tend to reach capacity quickly. For Magic Key Holders, the reservation window is slightly shorter, typically allowing bookings up to 90 days in advance. The process is managed via the "Make or Modify Park Reservations" tool on the Disneyland website or the official mobile app. If you are staying at an on-site Disney Resort hotel, linking your hotel reservation can sometimes unlock better availability. Since reservations are required alongside a valid ticket, checking the availability calendar before purchasing your admission is a critical first step in your vacation planning.
