We will be going in October. We did the Halloween party last year, and absolutely will not be doing it again. Incredibly long trick or treat lines FULL of adults!
A huge waste of VERY expensive tickets for a few hours.
In planning our 2014 trip we noticed as well that the parks hours calendar is not up yet. I am planning to just use last year's schedule (by day) to predict park hours for the time period. Not sure if the calendar will be up when its 180 days out and we begin making our dining reservations, but that is a HUGE factor when planning where we will eat. We want to catch the extra magic if possible.
