Matt, my mother and I went to the Haunted Mansion Holiday event on 10/3/2002. We bought event items (I got a watch, a great boxed pin set, and the event pins) They gave us 2 pins (Sandy Clause and Zero), a signed limited edition painting of Sally (only 500!) and another painting. We had dinner in the Blue Bayou (5 courses), rode the Haunted Mansion twice (which was remade for the Nightmare Before Christmas theme) and listened to a panel of voice actors for the movie.
Here is a photo album from the event!
Update: I added some photos of myself from Matt
