Hey there Patty (and Thomas)! Thanks so much for dropping by planDisney again and asking us a question.
I'm sorry to hear you are having trouble getting your
Disneyland app set up for your upcoming trip. If you are used to planning your trip with other people in your party in the Walt Disney World app, it is quite different from the Disneyland app. Unfortunately, we don't even have the option to link other Guests to our plans. After making plans for a Walt Disney World visit, I really wish we had that option. I'd be happy to share how I use the Disneyland app when I visit with family or friends.
If you are going to be visiting with your sister, I recommend that you each have a Disney account, download the Disneyland app, and link your own ticket to your account. You can also link each other's tickets into your app if you will be using
Disney Genie+. Tickets can be linked to more than one account. This will make it easy for either of you two to make a Lightning Lane selection for both of you at the same time. As far as
dining reservations go, only the person who books the reservation will see this in their app.
Patty, thanks again for stopping by. I hope this helps you plan your visit with your sister. Please stop by again with any other questions you have!
Carrie
