Hiya Renata!
Welcome to planDisney! The feeling of having two unused Walt Disney World Tickets must feel amazing. I'm sure you are excited to finally get to use it.
If you have two unused tickets with no expiration then know that
Walt Disney World Resort will honor them. You can log into your My Disney Experience Account and
change the dates. Unfortunately, if your tickets have an expiration date then you should know there is a chance it is no longer valid. You can try to
link your tickets if you haven't done so already and there probably will still be a need for you to make
Theme Park Reservations. On January 9, 2024, date-based tickets will no longer require Theme Park Reservations but it's not clear if your tickets will qualify.
If you continue to have trouble I would
reach out to the friendly Cast Members at Walt Disney World to help set you up.
If it works out I would try to time your visit for a visit to the Parks during
Mickey's Not-So-Scary Halloween Party. It is a special ticketed event but it is so much fun. You can trick-or-treat around Magic Kingdom Park while meeting your favorite characters in their Halloween costume while enjoying some amazing shows! It is a family-friendly event and not to be missed!
I hope you get a chance to visit and if you have any more questions please let us know!
Happy Planning!
