I got off the phone with Disney Reservations and they confirmed that park dining is not taking reservations after 5-6pm. The CM was kind of skirting around it which was a bit unusual so I asked her if it was due to COVID-19 which she said it was.Anyone feel free to correct me if there's been a change, but, I believe for all of November there has been no availability after 6:00pm at MK, HS, and AK. Something strange is going on that has yet to be revealed. I suspect it's more than a glitch because it's been going on several weeks. I've been watching it since I booked out ADRs for the 1st week in November, and nothing has changed since then.
