What is the experience like at toy story midway mania?

The only information given in the verified sources concerns the Disney‑Pixar Toy Story franchise and the character Jessie, a cowgirl rag doll appearing from Toy Story 2 onward. The sources detail her creation, voice actors, and role in the films, but they contain no references to an event or attraction called "midway mania". Consequently, there is no factual basis to describe what the experience might be like at such a location. Without additional data, any description of the experience would be speculative and therefore cannot be offered. For information about Toy Story attractions, one would need to consult sources that specifically cover theme‑park or fan‑event details.
