I'm just back from the party (Sept 30 and Oct 2) and make sure to hit Toon-town and the alice trail (back of toontown trail that leads to tomorrowland). I brought home just tons of candy.
Also get there early one day I got there at about 6:15 and the other at 5:00pm and they hearded everyone to Frontierland/Adventure/Liberty Square. Both nights I entered Fantsyland around 6:45 from Liberty Square and there were no lines. Nothing like riding my beloved Dumbo 3x in a row w/o getting off.
