Hello, Amy! Thanks for visiting the Disney Parks Moms Panel with your great question!
I recently traveled to Walt Disney World Resort, and I was in a similar situation. I am an
Annual Passholder (the unlimited
PhotoPass downloads are my favorite perk), and my sister is linked to my
My Disney Experience account. Although we were together for most of the trip, there was one morning when she and her two daughters went to
Magic Kingdom Park without me. Even though she scanned her own
MagicBand and I was not present, all her photos showed up in my account. Since she is not a Passholder, the images appeared in her account with a watermark; the ones in my account did not. I was able to download all the pictures, including attraction photos, and send them to her via email.
I called Disney Photo Pass today at (407) 560-4300 to confirm, and she mentioned that the pictures taken with your MagicBand will disappear from your sister's account 45 days after they are taken (typically
Passholder's photos have a one-year expiration). Your sister will definitely be a teensy bit jealous when she starts to get all those notifications while you're in The Most Magical Place on Earth!
I hope this helps, Amy! See ya' real soon!
