Welcome back Jacqui, to the Disney Parks Moms Panel!
Wonderful news! Your family can be linked to your Memory Maker and it's very simple to do!
First, they each should create a
My Disney Experience account , if they haven't already and each family member should be added to your friends and family list within your My Disney Experience account. Once their accounts are created, everyone must be sure to click the selection under the "Share Photo Pass" option. This will allow your brother and sister-in-law to add photos with the flick of their wrist with their Magic Band or admission card, linked to your Memory Maker! From there, photos can be downloaded and purchased by any one.
That's some awesome magic! Have fun taking pictures and creating wonderful memories!
Happy planning and enjoy your Disney vacation!
