We were at the 10/1 party and at MK around 1pm. They gave the arm bands out in front of the castle along with a map of the eve around 4:30. People that were coming in then had bags. A CM got one for us (very sweet), but there were a bunch at every trick or treat area. They told us to help ourselves to another bag if we filled one up! DD6, DS9, myself and husband all treated. The CM's were very generous. Some areas had lollypops and pixie sticks and others had butterfingers, full size snickers, twix, hershey mini's, m&m's, baby ruths, and more.....it was mixed up throughout the park. Have Fun!
