Sirita, welcome to planDisney, and thank you for trusting us with your vacation plans! First of all, I am so sorry for your loss. I hope that rescheduling your canceled Walt Disney World will bring comfort to you and your family.
The Theme Park Ticket that you cannot use will retain its value for you. However, this value can likely only be used to purchase a
Theme Park Ticket of equal or greater value. That said, you may find that explaining your scenario to a
Disney Cast Member via phone yields a different result. Either is worth the shot!
Sirita, I hope that this information helps you continue planning and dreaming. If we can help further, please do not hesitate to come back and see us! It would be our pleasure to help!
Wishing you many magical memories,
Clara
