ok, here's the official update from the HUB (internal CM site) I have not highlighted anything, this is how it's being presented:
In order to give Guests more time to enjoy the park, Extra Magic Hours at Disney’s Hollywood Studios have been expanded for Sunday, December 8 to 6am - 8am.
Offerings available during the additional time will be updated for our Guests in My Disney Experience. As a reminder, Star Wars: Rise of the Resistance is not included in Extra Magic Hours. Guests who remain in the park after Extra Magic Hours may have the opportunity to join a boarding group for Star Wars: Rise of the Resistance using the My Disney Experience app.
