Hi Kathryn! Thanks for visiting planDisney.
If you have prepurchased
Lightning Lane Multi Pass with your
admission tickets for
Disneyland Resort, you should see the ability to book return times once you've entered the parks. You can't pre-book these Attractions prior to your arrival, which is why you're not seeing anything yet. After scanning into the park, however, you'll be able to start booking return times for your park day! The earlier you arrive, the more use you should get out of the option, so be sure to check the park hours and set those alarms.
It is also possible to add this great option after scanning into the park subject to availability. Prices may vary. We do both depending on the circumstances of our trip, but we always go with this great add-on because we love spending less time in queues. Our little guys prefer to explore the parks rather than wait!
There are other great features on the Disneyland mobile app, which I hope you'll find useful, like mobile ordering food and beverages and checking wait times. Play around in the app once you've arrived to discover all the handy tools available to Guests.
I hope this helps!
Elizabeth
