Hi James! Welcome to planDisney!
As a parent of little ones, it is hard to wrap my brain around the thought that, one day, they will want to go off and explore the Walt Disney World Resort on their own. But I know that day is coming! The good news is that there is a ton for us parents to enjoy on our own, too, and I know you will have lots of fun as well!
Since your
Walt Disney World theme park tickets and
Disney Park Pass reservations should be linked to your
My Disney Experience account and already ready to go, finding each person's ticket number can be done via your account. Go to "My MagicBands and Cards" under the My Disney Experience drop-down menu on the Walt Disney World website. If you scroll down, you can see everyone under your account, and clicking on anyone's name will expand your view of all their tickets (cards) and
MagicBands. Match the 12-digit number that you see on the website to the back of each of your physical cards to know what ticket belongs to each person.
Your cards probably have a different design on the front that can be used as an identifier for who the card belongs to, but personally, I don't have enough room in my "mom brain" to memorize that! I take a permanent marker and write the first initial or name of each person on the back to keep track of who the ticket is assigned to. It is much easier!
I hope you have the best time with your family, James! Please let us know if you have any other questions.
