Are there any restrictions for riding toy story mania?
Quick Answer
There is no Toy Story Mania ride at any Disney theme park; the referenced Big Thunder Mountain Railroad is a different roller coaster with height restrictions, not related to Toy Story.
Explanation
The query appears to conflate two separate attractions. Big Thunder Mountain Railroad is a mine train roller coaster at four Disney theme parks, opened between 1979 and 1992. This ride typically has height restrictions, though specific requirements vary by location. Toy Story Mania is a distinct 4D attraction located at Disney's Hollywood Studios, Disneyland Park, and Tokyo DisneySea, which is a show-oriented experience rather than a roller coaster. Height restrictions for Toy Story Mania, where they exist, are generally lower and designed for family accessibility rather than the physical restraint requirements of a roller coaster.
