Hello, Amanda!
You have asked a great question! Yes, one person can purchase the
Memory Maker entitlement and switch the entitlement to another person. However, the switch is ONLY possible before the entitlement has been redeemed. Once redeemed, Memory Maker is associated with that account and only that person will have the 30-day unlimited download ability.
To make sure that all of your traveling party's Disney PhotoPass photos are included in the Memory Maker download, it is important to be linked via
My Disney Experience accounts. You can link and give each other permission to view and purchase photos under the Friends and Family tab. I suggest doing this before your vacation.
I hope this clears up any confusion with Memory Maker entitlements. Please let me know if I can answer any other questions you may have as you plan your vacation!
Enjoy making magical memories with your family!
Missy
