Unlike Universal or Ocean park, Disneyland does not have concept of express pass. However they do issue free fast track pass for certain key rides. Fast track pass kiosk are located besides those specific key rides. you just need to scan you ticket to get your free fast track pass, which will allot you specific time. you can enjoy other rides and come back these rides at your allotted time, without much queuing up. Only catch is, you can have fast track pass active for one ride at a time, so cannot collect token for all rides in one go, but still quite a time saving.
