On the share, if you link her as a friend on MyDIsneyExperience , then they will have full access to the entire process... they can add photos, and download photos, etc. It is very easy and seamless. Add each of their family members to your account as friends (you can limit their access to your plans, so they can't change your FP's) that way anyone who scans their magic bands with a photographer or gets an onride photo/video will have them linked and all in the same memory maker.
I have done this many times, and it works great. Its an awesome way to reduce costs. There is only 1 catch... the "FREE" memory maker entitlement from the new annual passes cannot be shared with people not on your reservation, however, I doubt that directly effects you.
