Each resort has it's planned events on Halloween night, along with characters in costumes. Last year my friend and I hopped from resort to resort to get pictures with the characters. All of them had a DJ, arts and crafts, and some kind of snack to make like decorate cookies. The stores also had candy for those that still wanted to walk around and trick or treat. If you're into pin trading also some stores had special pin trading set-up for Halloween.
