Choose which ride or attraction you want to experience most. Head over to that ride as soon as you enter the park.
Locate the Fastpass kiosks. They are usually off to the side of the main, or "stand-by" entrance for the attraction. Most are large, square metal boxes roughly 4 feet high.
Insert your theme park ticket into the slot in the Fastpass kiosk. A ticket with your return time will emerge. It will also tell you when you are eligible to get your next Fastpass ticket. You'll need to repeat this process for every member of your party, as each Fastpass ticket is only good for one person.
Return to the ride or attraction at the time on your ticket. Look for the Fastpass entrance. Someone at this entrance will check your ticket, while someone further in, closer to the ride's loading area, will collect it from you.
