The crowd as it exits on a party dayThere’s a theory that I’ve seen several places that claims that the Magic Kingdom is less crowded on days when Mickey’s Not-So-Scary Halloween Party or Mickey’s Very Merry Christmas Party is taking place. I honestly don’t think that’s the case anymore. The Magic Kingdom is always packed around both holidays, because people want to see the decorations. It might clear out a little bit early, but it won’t be empty.
