It looks like it is just the same concept as extended evening hours, providing access to designated rides that are open, except:
(a) Extended evening hours are currently available only to guests staying at supposed "deluxe" Disney resorts, which includes all the DVC resorts, and the Swan and Dolphin, but not the moderate or value Disney resorts. The new Disney After Hours will not have that limitation and will include anyone who wants to come including off-site quests, while on-site quests (including the moderates and values) will be able to get tickets starting Oct 4, three days before off-sites can start buying tickets.
(b) The current extended evening hours are only two hours long. The Disney After Hours will be three hours.
(c) Extended evening hours do not have any separate entry fee. You just need to be staying at an applicable resort and have a park ticket applicable to the day you go. The new Disney After Hours will have its own separate ticket that needs to be purchased; you will be able to enter the park at 7 p.m. before after hours begin and, beginning at 7, get on rides the same way as regular entry guests. Disney has published applicable event dates for between Jan and April 2023 and the ticket prices for Studios and Jan to March for Magic Kingdom, see for Studios

https://disneyworld.disney.go.com/e...c-kingdom-after-hours/#drawer-card-EventDates. There is also a page for Animal Kingdom but it says no dates or prices are available yet
https://disneyworld.disney.go.com/events-tours/animal-kingdom/animal-kingdom-after-hours/ There does not appear to anything shown yet as to whether Epcot will even have it.The price will vary according to night of the event (a) at studios from $129 to $149 per person (with no child discount mentioned), except that DVC members and Annual Passholders will pay between $99 and $129; (b) at MK, $125 to $159 per person, except Annual Passholders and DVC members $105 and $129 per person. There will be some limit to number of tickets sold.
(d) The Disney After Hours ticket, will, besides providing entry, allow you to get, without payment, some snacks such as popcorn and drinks at outdoors stands in the parks.
It thus appears that what this is is just another extended evening hours event but all those previously excluded can now get in, and everyone who goes has to pay a lot of money to get in. My major concern is whether this is the precursor to doing away with the free extended evening hours for those staying at resorts that currently can get it. In other words, has Disney just created another way to charge people lots of money to get into the park and will it it create a fee that DVC members will have to pay to be able to use any extended evening hours.
