Is there an official toy story meet and greet program?

The available evidence does not mention an official meet‑and‑greet event for the Toy Story franchise. The only references provided are a general entity for Toy Story and a Wikipedia list of characters from the films and related media. No source describes a formal program organized by Disney or Pixar for fans to meet characters or cast members. While fan‑organized gatherings and unofficial events may occur, they are not recognized as official by the production companies. Therefore, based on the current evidence, there is no confirmation of an official Toy Story meet‑and‑greet program.
