Hi Eric, welcome to planDisney!
You chose a great time to visit the
Disneyland Resort! Many amazing experiences are returning and looking at your arrival date, you'll get to enjoy them all! The traditional character meet and greets are returning, meaning Mickey and all his Pals will be ready to give out hugs and autographs! And the
Main Street Electrical Parade and
Disneyland Forever fireworks at Disneyland Park and
World of Color at Disney California Adventure Park are all returning on April 22, 2022! I’m excited for you!
Back to your main question. You can absolutely set up your grandchildren's
theme park tickets to be managed by multiple guardians. Please have all members of your party download the
Disneyland Mobile App and create their own account. Then you can add the grandchildren's tickets to each of your party member's Disneyland Mobile App. First, open the Disneyland Mobile App, click the three horizontal lines in the bottom right-hand corner, select "Tickets and Passes", and then select "Link Tickets & Passes". This will allow you to scan the barcode of each ticket that you would like to link. And you should be all good to go!
If you have any more questions before your trip, please do visit us again!
See ya real soon!
