Can you meet buzz lightyear and woody during celebrations?

The only verified fact about the voice actor Jonathan Harris is that he provided voices for the animated features A Bug's Life and Toy Story 2. The evidence does not mention any celebrations, nor does it state that Harris voiced the characters Buzz Lightyear or Woody, nor that any event would allow an encounter with those characters. Consequently, based solely on the provided information, there is no indication that a meeting with Buzz Lightyear and Woody during celebrations is possible or documented.
