Welcome to planDisney, Thomas! It sounds like you've got a fun visit with your daughter coming up next month, and it's a great idea to make sure that you're all linked up and ready to go in My Disney Experience before you get there.
Even if you have purchased tickets separately, you and your daughter can link up in My Disney Experience to make
dining reservations and
Lightning Lane selections together. Open up your
My Disney Experience app and tap on the main menu in the bottom right corner. Scroll until you see "My Profile," select that option, and toggle to "Family & Friends List" at the very top of the screen. Tap on "Add a Guest" and link to your party by entering their name and age or scanning their linking code. Once that's done, you'll be able to add your daughter to your existing plans and make more plans together! Since she has a
MagicBand linked to your account, make sure that she uses one that is linked to the account that she used to purchase her tickets. Alternatively, she can also use
Disney MagicMobile, which is my preferred way to access my tickets and Lightning Lanes.
I hope this answers your question, Thomas, and please let us know if there's anything else we can do to help you plan your magical vacation!
