Welcome to planDisney, Lyndon!
What a treasure you've got on your hands there, and how exciting that you'll be using your magical Disney World tickets soon! I'm happy to confirm that Walt Disney World
honors all unused theme park tickets that do not have an expiration date.
To use your tickets, you'll want to be sure and link them in your
My Disney Experience app. From the home screen, select the hamburger menu icon on the lower right "☰" and then select "My Tickets & Passes". Click the top right "+" to add your tickets, and then select "Link Tickets & Passes". Ka-chow... you are good to go!
Entering your tickets in the app will also enable you to purchase
Lightning Lane Passes, if you so choose. These allow you to skip the stand-by line on some of your favorite attractions, giving you additional time to enjoy other experiences in the park. My family has found when we purchase Lightning Lane Multi Pass at Magic Kingdom, in particular... we really feel like it allows us to ride all the rides!
If you need any help with linking the tickets, just give
Guest Services Ticketing a call with your ticket numbers. A friendly Cast Member can both verify your tickets, and assist with getting them linked to your My Disney account.
I hope this helps, and that you enjoy every pixie-dusted moment of your 4 day park hopping!
The magic is calling,
Tami
