Planning to attend Mickey's Not-So-Scary Halloween Party at Magic Kingdom Park this fall? You'll want to check availability sooner rather than later — as of August 13, a total of eight dates for the beloved after-hours event have officially sold out.

The seasonal celebration kicked off on August 7 and runs on select nights through October 31. With another date confirmed sold out on August 13, guests who haven't yet secured their tickets may find their options narrowing quickly.

Guests without a valid party ticket will be turned away on sold-out nights, so if you have a specific date in mind, it's worth acting fast before more evenings reach capacity.
