Hello, hello there, Alun! Welcome to
planDisney, where we love helping our fellow Guests plan magical Disney vacations. Thanks for stopping by with your question!
I hate to be the bearer of bad news, my friend, but since you purchased all the tickets, linked them to your
My Disney Experience account, and assigned them to each individual person in your travel party, there is no way for you to share the children's profiles to other adults within your party... or at least not by yourself!
Alun, let me explain how this works. The way My Disney Experience is set up, children's profiles need to fall under an adult's profile, which essentially means that this adult will be in charge of any and all plans including said children. In addition to this, since children under 13 are not allowed to create a My Disney Experience account of their own, they will not be able to connect with other Guests' profiles. In your particular case, you are the adult who's in charge of all children within your travel party.
Now, I did mention that you will not be able to change this by yourself, but you could always
speak to a friendly Cast Member over at 0800 16 90 730, which is the Disney Parks Tickets hotline. If there's anyone who could help you transfer the children's tickets over to a different adult, it's definitely the talented Cast Members!
I understand that this wasn't the news that you were expecting to hear, Alun, and I do wish I could do more to help you out. That being said, please don't hesitate to reach back out to us if you need any more help!
See you real soon,
Ana Paula
