For anyone who's interested, I've posted a full review of our visit to Mickey's Halloween Treat on October 13, 2006, including complete information about the event, treat stations (and new treats available this year), character photo ops, park decor, available merchandise, attractions and dining locations and shops open during the event, and tips for those attending the event on later evenings. Extensive photos included, including event park map.
