Welcome to planDisney, Linsey!
What a fabulous mother-in-law that you have! The gift of a Walt Disney World vacation is such an amazing thing. Really, she has given your entire family memories to cherish for a lifetime.
Linsey, your mother-in-law to connect to your husband through her My Disney Experience account by going to her
Family & Friends list. All she will need to do is to log in and send your husband an invitation to join her, the same way that she did for you. This will allow you all to see each other's plans and make reservations for the entire group.
The biggest issue you will run into is that a minor's profiles can not be shared among adult profiles. So you will have to decide if your mother-in-law will be doing the planning, or if you want to do the planning for your kids.
If you would like to do the planning for the group, she will need to transfer the tickets over to you. She can do this by calling the website support Cast Members at
(407) 939-4357.
I hope that this helped, Linsey.
Happy planning!
