Today, Tom Staggs confirmed that the next step in the Fastpass + roll out will go live. At present, guests visiting the parks can only book 3 fast passes each day. From Monday, guests will be able to visit a Fastpass + kiosk in the parks once they have used their initial 3 Fastpasses. This does mean that you may want to be thinking twice before booking that Big Thunder Mountain ride in the dark. Until that Fastpass is used, you won’t be able to book anymore.
At present, there is still no news if the new changes will also come to the My Disney Experience App.
