I actually brought up all the problems of logistics like, 5 pages ago, but it was totally ignored. In short, if they were to make HHN work this year, they would have to eliminate all those pass thrus (where you push through all those vertical hanging strips of cloth between scenes), allow only one party in the maze at a time to avoid traffic jams, and keep scareactors 6 ft away (pretty much making scarezones useless). Not to mention I don't know how they'd even have security in the mazes, given their typical close quarters and less than 6 ft away from guests.
Now on top of that add the layoffs, rising cases, and the noted lack of any sort of announcements, as well as some other parks already announcing the cancellation of their own Halloween events, and the outlook is pretty grim. Yeah, I know tents are going up, but since nothing has been announced, they can just quietly scrap it all and (hopefully?) save it for next year.
