Hi Daisy,
I can honestly say that
Mickey's Not-So-Scary Halloween Party is my favourite special event at Magic Kingdom Park. I attended the party last weekend, and had a SPOOKTACULAR time! There are so many reasons to attend Mickey's Not-So-Scary Halloween Party, I will give you my top reasons...
First, Mickey's "Boo-To-You" Halloween Parade only takes place during the party, and it is the a great mix of spooky fun with Disney magic. Happy HalloWishes Fireworks is an amazing fireworks display with a villainous feel set to some of our favourite songs from the Disney Villains we love to hate. These fireworks only light up the sky during Mickey's Not-So-Scary Halloween Party.
Also, when you attend the party, every guest is invited to Trick-Or-Treat in the Magic Kingdom. Several Trick-Or-Treat stations and trails are set up throughout the theme park, and are waiting for guests of all ages!
If you are a fan of Disney a Characters, there are plenty of Villains out and about greeting guests, there are usually some rare characters that make appearances, and plenty of familiar characters as well. Finally, I have found that the crowds tend to be a little smaller allowing for less waiting to ride your favourite attractions.
I would highly recommend attending Mickey's Not-So-Scary Halloween Party, I am positive it will be one of the highlights of your Walt Disney World Resort Vacation. Please let me know if you have any other questions, I would be happy to help!
