Hi Amy! We are so glad you decided to stop by with another great Walt Disney World vacation planning question!
Memory Maker is a product that allows you to download all your
Disney PhotoPass photos for one price. Ride and attraction photos and videos, dining location photos, and photos taken by Disney PhotoPass photographers are all included. You can even stop by the
Disney PhotoPass Service Studio at Disney Springs for even more photo memories of your magical vacation!
I am happy to let you know that while traveling with your sister's family, you will be able to download everyone's photos with the purchase of one Memory Maker. First, you'll need to be sure you are connected in your Family & Friends list in your My Disney Experience account. If you are not already connected, you can choose to "Add a Guest", enter the pertinent information, and invite your sister to connect. If she manages plans for her family, she can share her Family & Friends list with you, and you will be good to go! You'll be able to view and download photos for up to 25 members of your Family & Friends list. The best news is, you won't even need to be all together to capture photos! If the cousins ride Space Mountain while the parents get some iconic photos taken on Main Street, U.S.A., you'll have everyone's photos available to download. Isn't that great? Once downloaded, you may share the photos with your sister and her family however you like.
I hope that helps! Please feel free to visit us again if we can answer additional questions. Disney vacation planning is what we do best :)
