Hi There Penny,
Welcome to the Disney Parks Moms Panel! I'm a big fan of
Memory Maker and always purchase one each time my family visits the Walt Disney World Resort. It's a wonderful way to capture your entire family/group in all of your vacation photos! All photos taken by
Disney PhotoPass photographers are included, as well as Attraction Photos and Videos, Magic Shots, and Dining Photos. All photos that are scanned to your
MagicBand, and the photos of those in your party who have enabled photo sharing with you, will be available for you to download.
As long as your Memory Maker is linked to your account on
My Disney Experience and you have enabled photo sharing with everyone in your party within the "Family & Friends" list, then it does not matter whose MagicBand is scanned, you will all be able to use Memory Maker and will not have to purchase an additional one. Enabling photo sharing with everyone in your party will allow any photos taken to be shared on your Memory Maker should you need to split up during your trip.
I hope this information helps in planning your visit. Please stop back by if you have any additional vacation planning questions!
Magical Wishes,
Susan
