What year was toy story midway mania added to disney theme parks?

The provided evidence consists of a knowledge graph entry for Toy Story and a Wikipedia page listing Toy Story characters. Neither source contains information about the addition of the Toy Story Midway Mania attraction to Disney theme parks, nor does it mention a specific year. Because the query requires a factual year and no source confirms or contradicts a date, I cannot provide a reliable answer. Additional reliable sources would be needed to confirm the year of this attraction’s introduction.
