Hi there, Gaurav!
Thanks for bringing your question to the Disney Parks Moms Panel. I'd love to give you some more information about
Disney FASTPASS at the Disneyland Resort.
With Disney FASTPASS, you can bypass the standby queues at select attractions throughout the day to maximize your time in the parks. All Guests can use this service for no charge if you utilize the FASTPASS kiosks located next to these attractions. You would just insert your paper ticket into a kiosk, and you'll be given a reminder time when you can return to this attraction to enter the FASTPASS queue. Also listed on this reminder slip will be the time when you are able to make your next FASTPASS selection in the same manner. If you choose to add the
Disney MaxPass feature to your park ticket on the
Disneyland app, you can make your selections digitally right from your phone. This will save you footsteps and time so you don't have to be near an attraction to make your FASTPASS selection. The app will also give you the exact time you are able to make your next FASTPASS selection similar to the time on the reminder slips. No matter which method you choose, this service will really help you make the most out of your visit.
Since you can only make FASTPASS selections once you enter the park and not before, you are correct that you can begin making your selections when the park opens, and you will also be given the time that you can make your next selection. I recommend setting an alarm on your phone so you don't miss a minute of the magic by making as many FASTPASS selections as possible all day long. You will be amazed at just how much you can experience using these features.
Another great time saver for us on the Disneyland app is the mobile order feature which allows you to skip the line at select Quick Service restaurants in the parks. You can order and pay for food and beverages right from the app. It's such an awesome feature that has really helped us maximize our time.
Have a magical day, and feel free to drop by if you have any other questions!
