How long has toy story midway mania been operating at disney s hollywood studios?

The provided evidence discusses the Toy Story franchise and its characters, but it does not mention a theme park attraction called "Midway Mania" or its operation status at Disney's Hollywood Studios. Without reliable sources indicating when or if this attraction was opened or closed, I cannot provide a factual answer. If you can provide additional references or sources that mention Midway Mania directly, I would be able to give a precise response.
