Is there anything Disney that is not fun? It is great.

There are lots of people dressed up in costumes, tons of characters in the park, a lot you never see, like the villians.

(You may even spot Maleficent) (she and I are very close) Everyone gets trick or treat bags and there are spots where you can go trick or treating. The park is decorated, the parade is different, and lots of fun. If you go early in the month the park is not very crowded so you can do a lot of things in the Magic Kingdom. This is our second time to go and we are really looking forward to it.
Do not miss the Headless Horseman. Quick but AWESOME.
