Hey April!
Welcome back to the Disney Parks Mom Panel! Thank you for bringing us this great question.
You are correct. As long as your entire traveling party are linked via the Friends and Family feature in your My Disney Experience account, you will be able to view all the
Memory Maker photos they capture with their Magic Bands or PhotoPass card.
The ride photos offer the same feature. Any of your traveling party can visit the ride photo counter after exiting the attraction to have their photo connected to their Magic Band or PhotoPass card. You, as the Memory Maker 'owner', will then be able to view, customize and download those pictures.
I hope this helps with your planning. If you have any other questions please come back and see me.
Wishing you a magical vacation and a pixie-dusted day!
