Disney have announced that during the month of September 2019, guests staying in any Disney resort hotel will get many more Extra Magic Hours.
Star Wars: Galaxy's Edge at Walt Disney World officially opens on August 29, 2019. August 29 - August 31 there will be no Extra Magic Hours for Hollywood Studios, but the park will open at 6am for all guests for those first few days.
Hollywood Studios + Star Wars: Galaxy's Edge
Extra Magic Hours will take place every day from September 1, 2019 - November 2, 2019. Extra Magic Hours will run daily from 6 - 9am. During this time Star Wars: Galaxy's Edge, Toy Story Land and other select attractions will be open. (Star Wars: Galaxy's Edge and its experiences subject to capacity.)
This is a good tactic to get people to stay on site, because if the park opens at 9am and Star Wars: Galaxy's Edge is at already capacity to hotel resort guests, you're out of luck.
Disney's Animal Kingdom
Extra Magic Hours will take place every day from August 29, 2019 - November 2, 2019 from 7 - 8 am. (Featuring Pandora – The World of Avatar and other attractions throughout the park.)
Magic Kingdom Park
Extra Magic Hours will take place every day from August 29, 2019 - November 2, 2019 from 7 - 8 am. (Featuring favourite attractions in Fantasyland and Tomorrowland.)
