Greetings, Paul, welcome back to the Disney Parks Moms Panel, we thank you for this excellent question!
How wonderful it is that you'll be experiencing and creating magical memories together with your extended family!
Through Disney's
Memory Maker photo downloads, you'll be able to download your own Disney PhotoPass photos and those of
Family & Friends who share media with you. All you have to do is invite your in-laws to
Plan and Share through your
My Disney Experience account. If everyone in your travel party is linked, then everyone will be in the Disney PhotoPass photos at all Disney Theme and Water Park locations
provided everyone
has proper admission via a MagicBand or Disney Theme Park Ticket Card. If you are dining at Disney Resort hotels, just make sure that if you take a Disney PhotoPass photo with your in-laws, be sure to ask the photographer to link it to your own MagicBand, Disney Theme Park Ticket Card, Disney PhotoPass Card, or Memory Maker Card. Photos taken during the Memory Maker Window will be linked to your Memory Maker Disney account by doing so.
Did you know about the current, time-limited
Canadian Multi-Day Ticket Offer? You may wish to consider this spectacular offer for your in-laws so that they may gain access to all Disney Theme Parks and be in all the Disney PhotoPass photo moments with you.
We hope this information is helpfu and wish you all a magically memorable Disney vacation!
Jacqueline
