How often do toy story characters appear in disney parks?

The only confirmed information in the provided sources is that Toy Story is a Disney and Pixar franchise with multiple films and a list of characters. There is no mention in those sources of any appearances of Toy Story characters in Disney theme parks, nor any data on how often such appearances might occur. Because the evidence does not address the question, we cannot state a frequency or even confirm that such appearances take place. Any claim about the presence or absence of Toy Story characters at Disney parks would be speculative and is therefore omitted to avoid misinformation.
