Hi there, Zach, and welcome to
planDisney! Thank you so much for trusting us with your vacation planning question!
I'm very happy to report that you definitely do not have to remove their names from your My Disney Experience Family & Friends list in order to add them to the existing reservation. Simply open the
My Disney Experience mobile app, click on the three lines at the bottom right corner of the screen, scroll down until you see the Account section, and click on Profile. Once here, head to the Family & Friends List tab and click on one of their names!
You should now be able to see their name and age followed by "Plans Managed by Me". If you go down a bit, you should see an option to "Connect with This Guest". Simply click on the easiest option for you and go from there. I always pick the "Send Email" option, but you're welcome to scan their linking code too! Once they accept your invitation, their My Disney Experience accounts will be linked to yours under the original profiles you created, and you'll be able to add them to your hotel and dining reservations from here on out.
If you experience any technical difficulties with this or anything else, please
call the Disney Resort Hotel Reservations and Tickets hotline so a friendly Cast Member can help you out! In the meantime, please don't hesitate to reach back out to us with any other questions you may have. Have a magical day!
Warm hugs,
Ana Paula
