This is a special hard-ticketed event that takes place throughout the month of October at the Magic Kingdom. Hard-ticketed means you need to purchase a ticket specifically for this event. It lasts from 7-midnight. On the days of the party, the park will close at 6 for all regular guests. Those attending the party are usually allowed to enter after 4 pm with only their party ticket (no other admission required). Almost all rides are open during the party. There is a special halloween parade, trick or treating, face painting, and other Halloween activities. The characters are also dressed up in Halloween costume. It is a really fun event. I attended for the first time last year and will be attending on three different nights this year.
