They've been releasing park hours once a week, usually on Friday afternoon, about 70 days beforehand. This past Friday, April 29, they released park hours up through Monday, July 11. They post changes to park hours (i.e., if parks will open earlier or close later) about 2 weeks out and also will sometimes change park hours the days before or even the day of.
Early entry is now every park, every day, 30 minutes before regular opening time for each park, for all Disney resort guests and certain specified offsite resorts.
Deluxe Extra Evening Hours, for guests of Disney deluxe resorts and certain specified non-Disney resorts, are posted on
this web page and updated once a week, again, usually on Friday afternoons. Currently that schedule goes through Wednesday, July 13.
So, you have some time to wait before November dates are posted. Just keep checking
MDE and the website for updates as time gets closer.
