Hi, Darlene!
Welcome to the Disney Parks Moms Panel! Thank you so much for stopping by to ask us your question.
To see if you have any valid theme park admission days, visit your
My Disney Experience Account on the Walt Disney World® Resort Website - your tickets and MagicBand are both linked to your account. You'll see the icon on the top right of the home page. From the drop down menu, select My Reservations & Tickets and scroll down until you reach Tickets & Passes. This is where you'll find if there are any theme park admission days available for you to use.
Keep in mind, most theme park admission tickets expire 14 days after first use, but there are a few exceptions, so it's definitely worth looking into! If you're not able to find this information on your My Disney Experience Account, you can always call the customer service number dedicated to questions regarding existing theme park tickets at (407) 939-7523, a Cast Member should be able to research your account.
I hope this helps you, Darlene! Please let me know if you should have any additional questions. I am here to help!
