Hi. DW and I were at WDW for Halloween 2002. We always spend some time resort hopping and from what I recall, there were Halloween displays (Jack-O-Lanterns, etc.) at almost every resort. Of course, the decorations are not as extensive as those for Christmas, but the answer to your question is, yes- there are Halloween decorations at the resorts. I also remember that there were Halloween-related kids activities at most resorts as well.
