Hi Wendy,
Thanks so much for visiting the Disney Parks Moms Panel with your question!
Mickey's Not-So-Scary Halloween Party (MNSSHP) is my all-time favorite special event at Walt Disney World! I know you're going to have a spook-tacular time!
As you already know, the official start time for MNSSHP party is 7:00 p.m. and the fun runs until midnight. In the past, Guests have been allowed entry into Magic Kingdom as early as 4:00 p.m. with party tickets, so that might be a possibility again this year. I haven't seen an official schedule of party events for 2014 yet, but I'd expect them to be similar to the 2013 schedule, which I've included below for you.
Disney Villains' Dance Mix and Mingle! - 7:45 p.m., 8:50 p.m., 10:05 p.m. and 11:15 p.m.
Mickey's "Boo-to-You" Halloween Parade - 8:15 p.m. and 10:30 p.m.
Celebrate the Magic - 9:15 p.m.
Happy HalloWishes - 9:30 p.m.
Wishing you no tricks and lots of treats during your visit, Wendy! Please let me know if you have any other questions as you make your plans.
Beth
