For us and many others, Halloween Time at the Disneyland Resort is one of the most special times of the year. It generally runs mid-September through Halloween with special decorations, surprises and special ride features. This year, Disneyland Halloween Time begins Sept. 9, 2016, and runs through Oct. 31, 2016. While some of the fun festivities are included with Halloween Time, Mickey's Halloween Party is not. The parties, which are held on select nights during Halloween Time, require event tickets.
