What are the criteria for disneyland to host a toy story event?

The only verified evidence available is the existence of the film Toy Story. No documented source provides details regarding Disneyland's policies, requirements, or procedures for hosting events related to that property. Without such evidence, it is not possible to describe the criteria or steps Disneyland would need to meet. For accurate and up-to-date information, consult official Disneyland communications or reputable news outlets that cover park programming.
