Hi Aimee! Welcome to the Disney Parks Moms Panel!
Your daughter is going to have SO much fun with her friends soon! I know she will make many special memories and I'm glad she is asking about
Memory Maker to capture them!
In order to share Memory Maker and any other plans that they are making together, your daughter will need to have her
My Disney Experience account linked with her friends' My Disney Experience accounts. I've done this on a few trips with friends myself and it is very easy! Once logged into her My Disney Experience account (or your account if she is on your account), go to "My Family & Friends" from the My Disney Experience drop-down menu. Scroll to the bottom and click "Add a Guest." Then choose "I'll enter their name and age." Once you put in the information for her friends (or their parents if her friends don't have their own accounts) and select the age, an option should pop up to "Invite this Guest to connect." Then, you can enter the email address that is associated with their My Disney Experience account. Once they have accepted the invite, your accounts will be linked.
Your daughter's party can then decide how to divide the Memory Maker purchase and designate who will purchase it. One Guest will make the purchase, but as long as everyone is linked in My Disney Experience and have chosen to share
PhotoPass photos, everyone's PhotoPass photos will show up in Memory Maker.
I hope this helps a bit, Aimee! Please let us know if you have any other questions.
