I have purchased Memory Maker. How do I manage which member of my group it is assigned to?
PhotoPass – Frequently Asked Questions
Before you download any photo or otherwise redeem your Memory Maker purchase, you can reassign the Memory Maker entitlement to any person who has a Disney account and who is connected to your Family & Friends list. Once assigned, that individual will become the owner of the entitlement.
If you do not see Memory Maker in My Reservations, you may need to first link it to your Disney account.
