Halloween at Disney, Trick or Treating at resorts?

[butfirstdisney]

Hi Everyone! I will be going 'Home' to Walt Disney World with my husband and 2 kids on October 30th this year. We will be there through November 8th. My son is 7 and my Daughter is 1. Does anyone know if there will be trick or treating anywhere on property on Halloween night besides the Halloween party at Magic Kingdom? At any of the resorts or parks? We want to go to MNSSHP but it is SO EXPENSIVE! It will cost us approximately $330 for 2 adults and 1 child (my daughter is free) just for the tickets to the party. Any tips or advise would be appreciated. Thanks disFriends!
