Hi there, Julie!
Thanks so much for stopping by with this great question!
So I have actually run into this issue myself, and what I discovered was that a
minor's My Disney Experience profile can not be shared between adults. But Julie all hope is not lost! You can transfer their accounts from your mother to yourself by calling
(407) 939-4357, however, if your mother would like to make any other plans for them, you would have to transfer them back to her.
What may be easiest, and what I found works best for my family, is to share
My Disney Experience Accounts between yourself and your mother. Alternatively, your children can have profiles under both adult accounts; however, know that they will not be able to share tickets between the two accounts.
I hope that this answered your question, Julie.
See you real soon!
Sarah B.
