Hello Mindy! Welcome to the Disney Parks Mom´s Panel.
Mickey´s Not-So-Scary Halloween Part is an awesome experience to enjoy while at Walt Disney World.
My family really enjoys the decorations and all the special activities, but the best part is the crowd level that can be experience at these events. Try to be well rested for the party, so that you can make the most of the late hours.
The schedule of attractions, shows and events will be online around the first day of the party (September 10 2013).
At that time the schedule might be at Disney´s web site or at unofficial sites like Allears or Wdwinfo.
If interested in the candies, you should go early to the Trick or Treat Locations around the park.
I also recommend viewing the second parade, for a lower crowd level.
The Pirates League is a great activity to add for the day of the party. Captain Jack´s crew will make you look like a pirate or mermaid and also feel like one.
Glad to help you plan a magical and not-so-scary Disney vacation.
Hope to hear again from you.
Miguel
