Planning a fall trip to Magic Kingdom around Mickey's Not-So-Scary Halloween Party? You'll want to check availability sooner rather than later. As of July 30, seven party nights are completely sold out, with October 9 becoming the most recent casualty. It joins opening night (August 7), August 11, August 14, August 18, October 13, and Halloween night, October 31 — none of which can be booked any longer.

The good news: every September date is still open as of this report, along with a healthy spread of August and October evenings. Available August dates include the 21st, 23rd, 25th, 28th, and 30th. In October, options remain on the 1st, 2nd, 4th, 6th, 8th, 15th, 16th, 18th, 22nd, 23rd, 25th, 27th, and 29th.

Tickets for remaining dates run $139 to $224 for adults and $129 to $214 for children nine and under — a shift from the original launch pricing. Annual Passholders and Disney Vacation Club members can trim $10 off select nights through early October, and children two and under get in free with a paying adult.

The party runs select nights from August 7 through October 31, with the official event hours set from 7:00 p.m. to midnight, though ticketholders may enter Magic Kingdom as early as 4:00 p.m. The evening features trick-or-treating, character meet-and-greets, ride overlays, exclusive food and merchandise, the Hocus Pocus Villain Spelltacular, Mickey's Boo-to-You Halloween Parade, and the Not-So-Spooky Spectacular fireworks over Cinderella Castle.

New this year, Walt Disney World is debuting a Tomorrowland masquerade inspired by the 2002 film Lilo & Stitch. This report was originally published by Disney Fanatic.
