Hi ya, Dan!
Thanks so much for your question! Visiting the Disneyland Resort with my dad is still one of my favorite things to do, I hope that you and your son will be enjoying the park together. Just like Goofy and his son Max, right?
Disneyland Park tickets can totally be linked to more than one Disney account. If you open the
Disneyland Mobile App and tap on the "☰" icon that will open the main menu, where you can select "Tickets and Passes" to see your tickets. Each ticket has a barcode, and underneath the barcode is an ID number. To link the ticket to his account, that's the number your son will need!
On his own version of the Disneyland Mobile App, your son should tap the "☰" and go to the "Tickets and "Passes" section. He'll need to choose "Link Tickets and Passes" (tap on the "+" at the top right if you don't see that option right away) and then choose "Type ID" from the top menu bar. In the "ID Number" box type in the ticket number. That's it!
If you and your son are looking for an adventure, I have to recommend the
Adventureland Treehouse! This classic attraction has just reopened and it is
overflowing with details that could keep me exploring for ages. It's the perfect destination for a father and son to visit together!
I hope this answer helps you navigate your technical challenge with ease, Dan! I know my dad always has all the answers for me and I think your son is very lucky to have a dad like you.
Keep moving forward!
Amanda
