Hello there Crystal,
Welcome to planDisney - we're so glad you stopped by and thanks for submitting this great question! It looks like you're visiting the same day that I'm answering your question - how exciting!
I'm happy to share that you absolutely can easily share
theme park tickets with other members of your party when visiting the Happiest Place on Earth all through the
Disneyland Resort mobile app.
To do this, you and your friend will want to make sure you have the app downloaded to your phone and that you each log in through your own personal MyDisney accounts.
Next, your friend will want to tap the menu button (the three horizontal lines) and select "My Tickets & Passes." Then tap "Link Tickets & Passes." From here, your friend will just either want to scan the ticket barcode or manually enter the ticket ID to link the ticket straight to their mobile app.
Once the ticket is linked, your friend will be able to see and use their ticket easily and conveniently through the app.
Thanks again for stopping by with your question, and I hope you and your friend have a wonderful time visiting the Happiest Place on Earth.
Have a Magical Day,
Greg
