How many players can ride toy story midway mania at once?

The only verified information in the evidence concerns the characters in the Toy Story franchise, not the details of amusement park attractions. There is no mention of Toy Story Midway Mania, nor any specification of how many riders it can accommodate. Because the question asks for a specific number that is not present in the cited sources, we cannot provide a factual answer. Further research or an official source would be required to determine the ride’s capacity.
