Lets just look at those terms of service that are part of every admission media purchase:
Parks, restaurants, attractions, recreation, FastPass+ selections, entertainment, and other products, services or items are subject to change without notice, cancellation, and may close temporarily due to rehabilitation, refurbishing, capacity, seasonal, inclement weather or special events and may otherwise change or be discontinued without notice and without liability to the owners of the Walt Disney World® Resort. Ticket media is not valid for special or premium events or other activities which are separately priced. Admission entitlements are non-transferrable, not for resale, and must be used by the same person on any and all days. Age restrictions apply for access to certain facilities. Guests must be 21 years of age or older with valid proof of age to redeem alcohol entitlements.
It doesnt say that if Dumbo isnt spinning around in circles, you get a free premium Mickey Bar from Walt's Cryovault.
