Early release operating hours for the Magic Kingdom suggest an August 13 debut for the 2020 Mickey's Not-So-Scary Halloween Party season at the Magic Kingdom.
If August 13 turns out to be the opening night, this would be the earliest start, with 2018 beginning August 17, and 2019 on August 16. You can view the Magic Kingdom operating hours here.
Tickets went on sale on January 15 last year, so expect to have officially confirmation of dates and pricing very soon.
