From June 21st on, guests will no longer scan their FASTPASS ticket at eligible attractions; they will now need to scan their admission ticket or annual pass for access to the FASTPASS line. Paper tickets will still be important to schedule return times and serve as reminders to guests.
Guests may notice testing taking place at FASTPASS locations as early as June 19th.
Disney MaxPass will allow guests to download unlimited high-resolution PhotoPass images through the Disneyland App, and for the first time, guests will be able to use the Disneyland App to book and redeem Disneyland FastPass reservations. The cost will be $10 per day, and annual and daily options will be available for annual passholders.
