Hey there, Christian!
Thanks so much for stopping by the Disney Parks Moms Panel with a question for us. I'm always happy to help a fellow Tennessean! It sounds like you are planning a grand family gathering at
Walt Disney World Resort, and I'm sure you are getting excited. I know you will have a fabulous time visiting with all of your family. There's definitely no better place to make magical memories with your loved ones!
As far as online check in goes, you'll only be able to check in for reservations that are linked to your
My Disney Experience account. If your other family members have created their own My Disney Experience account, you can send a request to link to their account and then ask them to share their plans with you. However, I don't believe this will allow you access to complete the online check in but rather only allow you to view the reservation details. So you'll probably have to walk them through the steps in order to get it done.
I hope this helps and please be sure and let us know if we can do anything else. We're always here if you need us. Have a wonderful time on your upcoming vacation!
