If you have a memory maker during this event, the photos are edited excellently in the Halloween theme. It's pretty cool.
Special Foods and Desserts:
Disney has themed food and snacks it's so great. The candy corn ice cream is delicious!
They have special Characters that come out on Halloween that don't come out any other day at the park, such as Jack Skellington & Sally and Elvis stitch. Mickey Minnie and the gang have different costumes every year.
Hocus Pocus Villain Spelltacular:
This show is excellent. Make sure to go to the last showing since most kids are too tired to stay up by then, and it's got fewer people. It is shown at 7:40 PM, 8:35 PM, 10:45 PM, and 12 AM. The 7:40 showing is the fullest.
Happy Hallowishes Fireworks:
The most impressive fireworks! It's so great! They have this only once that night at 10:15 PM; people usually leave right after this show.
Mickey's "Boo-To-You" Halloween Parade:
This parade features unique Halloween-themed floats and appearances from rarely-seen characters like the Gravediggers and Hitchhiking ghosts. The parade occurs twice, at 9:15 PM and 11:15 PM. I recommend going to 11:15 because you can catch a seat for it right after the fireworks. Get a seat on the sidewalk near Casey's Corner.
