Memory Maker-sometime referred to as Photopass as well is a great investment. I highly recommend it for many reasons.
1-You can have everyone in your pictures
2-You can get all the photos from rides that have them
3-You can view them almost immediately after they are taken
4-You can link the Memory Maker to My Disney Experience so you don’t have to be together to get photos
5-This is my favorite- when you get home you can add borders and stickers-this is great fun!!
IMPORTANT- Buy before you go and make sure everyone is linked to it through My Disney Experience.
Enjoy your pictures and memories!!
