Oh Kathy!
What fun you are going to have on your family vacation to the Most Magical Place on Earth.
The first thing that you will want to do is to establish your own
My Disney Experience Account.
Here, you will be able to connect with your daughter on your
Family & Friends list so that you will be able to share plans. To connect with your daughter, log in and go to "My Family & Friends." You should see a blue "Plus" that says "Add a Guest." Once you click this button, you will be able to input your daughter's email and send her an invitation to connect with you.
Kathy, once you connect you will be able to see and share plans, but you will not be able to make a payment on her behalf. I recommend that you either pay her cash, or give her a payment for the vacation in the form of a
Disney Gift Card, which can then be used to pay for your
hotel,
theme park tickets, and almost anything else in the parks!
I hope that this gave you a bit of guidance, Kathy! We here at planDisney are always here to help, so please let us know if you have any other questions!
