Hi Rachel! Welcome to planDisney!
I'm happy to hear that you're extending your stay and enjoying some time at the Walt Disney World Resort as a family. There is no place better to spend quality family time than at the Most Magical Place on Earth!
Without knowing the exact ticket type that your kids currently have, I would assume the easiest path forward would be to purchase new park tickets for the extra days you will be there. It's quite possible that the school provided a special ticket offer that may be difficult to modify. To know for sure, you can
call the Existing Ticket line and speak to a Cast Member for assistance. They will be able to determine if this is an option and provide costs to modify the tickets. If you provided the original tickets and it was not purchased through the group trip, then it should be fairly easy to make changes.
Purchasing park tickets is as simple as it has ever been. You can buy them online and link them directly to your My Disney Experience account. Once connected, make sure to download the
My Disney Experience App to your mobile device to utilize
Disney MagicMobile. This will allow you to use your mobile device as your park ticket for entry. Simply tap your device when the Cast Member directs you to do so and you'll be on your way. It's a quick and efficient way to enter.
Rachel, I hope this information helps you plan for your stay! Have an amazing time making magical Disney memories with your family!
See ya real soon!
Greg
