Hi Gabrielle,
Welcome to planDisney!
I am excited to see that you all seem to be planning a visit to the Walt Disney World® Resort! If I understand your question correctly, here is my suggestion. Using the My Disney Experience Mobile App, send an invitation to connect to the parent who manages the account. In the mobile app, scroll down to find My Profile, click on the tab for Family & Friends List, and then click on the plus sign to Add a Guest. When you add that guest, select the option to share All My Plans.
Next, go back to your Family & Friends List, scroll down, and select the option that says Yes, share My Family & Friends List. Have your parent who controls the other account to also select that option so that, now, you both are sharing your Family & Friends Lists. Once you both have done that, you should be able to go back to Add a Guest and you should be able to select your other parent and brother from a list that automatically populates. If you still cannot see them to add, I suggest that you and one of your parents
call to speak to a cast member in Website Support. They can see the details of your accounts and provide additional assistance!
As you continue to make plans, take a look at the information about
Lightning Lane Passes and
Virtual Queues. Once you are connected in My Disney Experience, you should be able to see any Lightning Lane selections and Virtual Queues you have managed to reserve. Finally, if one of you has purchased
Memory Maker, and as long as your accounts are connected, that person should be able to digitally download your photos taken with
Disney PhotoPass® Service photographers.
Gabrielle, I am sending a little extra pixie dust trusting that you will get those accounts connected!
Magic and memories,
Donyell
