For Oct/early Nov, no dinners on party nights were released until this last Friday (not even reservations as early as 4pm!). On Friday, CRT dinners on party days became available. You can make a reservation through the regular CRT page for dinners between 4-6pm. I believe since party goers can enter MK at 4pm, they can book those early dinners without park tickets that day. Park goers who do not have party tickets can make reservations up until 6pm. They will simply be escorted out of the park after their dinner. This has been confirmed by a dining CM. Those planning on attending the party can book from 7pm on through the party dining page. You do not already need to have a ticket to make the reservations after 6pm but will need the tickets to actually attend the reservation. Some parties can sell out so it would be best to buy a party ticket if you do get a reservation after 6pm. Hopefully someone else can provide info on what dates in Nov were released. I know through Nov 9 dates were released on Friday but didn’t look ahead. I will say that the party night CRT reservations for the night I was interested in were gone within about a day of opening, so make sure you’re checking often!
