Hi there Tonia,
Welcome to planDisney from a a fellow Arizonan and thank you for your question! It looks like you'll be at the
Happiest Place on Earth in just a few days - how exciting!
It sounds like you'll just need to link your tickets in your son's
Disneyland Resort mobile app so that he can also have access to his ticket to enter and exit the park. To do this, you'll want to open the mobile app on his phone, select the menu button (the three horizontal lines) then tap "My Tickets & Passes."
In this next screen, you can select "Link Tickets & Passes" near the top right corner of the screen and then you'll have the option to use the phone camera to scan the ticket barcode or you can manually type the ticket ID in the "Type ID" tab. Once it's linked, your son will see the ticket in the "My Tickets & Passes" section of his mobile app!
As an added tip, one thing I like to do is take a screen shot of my
theme park ticket and set it as my phone background. That way, when I go to the entry gate for a park, I just need to turn my phone's screen on so that the Cast Member can scan it instead of pulling up the Disneyland Resort mobile app!
Thanks again for your question, Tonia! I hope you and your family have a wonderful visit to the Disneyland Resort.
Have a Magical Day,
Greg
