For 25 nights during September and October Mickey’s Not So Scary Halloween party (MNSSHP) takes over the Magic Kingdom at Walt Disney World from 7:00 pm until midnight.

This hard ticket event (meaning that the Magic Kingdom closes and you must purchase a special ticket for just this event) is a fun filled evening of trick-or-treating, characters in special Halloween costumes, a special “Boo-to-You Halloween parade, and capped off with a “Happy HalloWishes” fireworks presentation.

This is the only time that all guests, young and old, are encouraged to wear costumes to the park. Keep in mind the Florida weather can still be quite warm when choosing your costume. You should also wear something that is easy to move around in and safe while enjoying the rides. Costumes are optional, but they help you get into the Halloween spirit.

These special evenings have a limited number of tickets available for each night guaranteeing that the park will not be crowded and lines for rides will be very reasonable.

All guests (not just children) are encouraged to trick-or-treat at the 13 stations set up around the park. You will collect a variety of candy treats in miniature sizes typical of what is handed out for your local treat-or-treaters.

If you are a person that can’t get enough of the Disney villains then this is the event for you. They have their own special area in front of Cinderella’s Castle where they perform what is called the “Villains’ Mix & Mingle” 4 times nightly and are available for autographs and photo opportunities.

The Boo-to-You parade is well done and can only be seen by attending one of these events. It is performed twice nightly at 8:15 pm and 10:30 pm.

The 2nd parade is usually less crowded, because those attending with young children will often go home before the 2nd parade. Seeing all of the characters in their Halloween costumes is quite enjoyable.

Parties which run from 7:00 pm until midnight are slated for Sept. 5, 9, 12, 16, 19, 23, 26, 28, 30 and Oct. 2, 4, 5, 7, 9, 10, 13, 16, 19, 21, 23, 24, 26, 28, 30, 31.

To purchase advance tickets, guests can call 407/W-DISNEY

Personally, I think this is a fun event that everyone should try at least once. I would also recommend going in costume to put your self in the proper spirit.
