How to get fats passes

Download the Disneyland app and you can add fast passes for your whole group. There's an extra fee when you buy the ticket but then you can get the passes through the app. There's still a limit as to how many at one time

That's right

There are a limited number you can get per day. There are kiosks near (but not next to) the entrances to the rides. Scan your ticket and one will print out for you. You'll then need to return to the ride at the time designated on the ticket.

Now you can buy them at the ticket booth or in the machines located outside some attractions
