Yes! It's a great use of memory maker!
Everyone who has an
MDE account needs to link to each other through the Friends and Family list. Once in each others' list, make sure you select the option "this person can view and purchase my photos" next to each person (by going into Friends&Family, clicking on edit next to their name, click on the photos option).
A quirk when I used it and I'm not sure whether it has changed: everyone will be able to see everyone's photos when they click on the Photopass area of MDE, except our ride photos showed up weird. The person who purchased Memory Maker could see everyone's ride pictures, but the rest of us couldn't see them when logged in to our own MDE. That meant we would still get the download, but we couldn't look at them without the purchaser logging in for us.
At the end of the trip, the Memory Maker purchaser is the only one who can do the download - anyone else trying would be propmpted to pay. That means no one should bother doing edits likadding borders or stickers in their own login, because those don't translate/display in everyone's account. The purchaser will either need to do all the edits or share their login so others can do their own.
Hope that helps
