Hi Sienna and welcome back to the Disney Parks Moms Panel!
You do have some options when connecting to Family and Friends on
My Disney Experience. You can choose to allow your connections to view "All My Plans" or "Only Our Shared Plans" but you must choose one of those. Then you must also choose whether or not to share "My Disney PhotoPass Photos." If you want to share
Memory Maker with your traveling group you will need to be sure you allow them to share your PhotoPass Photos. One quick reminder, only one person may download the photos with Memory Maker.
If you are concerned about someone accidentally changing your plans, I recommend going through your Family & Friends list on My Disney Experience and making sure you are sharing "All My Plans" with those you are sure won't make that mistake. I will say, I have many of my friends connected on My Disney Experience and I haven't had an issue with someone accidentally changing my plans. I hope this will be true for you as well!
Sienna, thank you for visiting us with another great question. I hope you'll let us know if we can help you with any other questions!
Wishing you a magical vacation,
Amy H.
