Something to note: the Halloween Haunt page on Kings Island's website currently does not contain any body text.  The header image (with the hand) and the image gallery are there, there is just zero body text or anything on there to describe the event. It's very likely that there's just a delay in publishing an updated version of this webpage. Who knows, maybe with the new Six Flags app and websites, we'll see the Legacy Cedar Fair websites get a new look as well. If that's the case I'd assume parts of all of the websites might be in some kind of weird flux until they're officially needed.  Cedar Point's website apparently briefly showed a description for their new The Conjuring: Beyond Fear attraction, though currently the HalloWeekends page is just a bare bones description of the event. 

Delirium is certainly not revolting! Sure it may not be the cutest ride in the park, but that is no reason to call it revolting!! Maybe it's trying to get some attention because it would like a fresh coat of paint     As a reminderfor anyone who's still upset: "Sherwin Williams presents The Eiffel Tower", "BankAmericard Service Center", "North American Van Lines Locker and Storage", "Rainbo Backerei" (I think it was a brand of bread), the "Marathon Turnpike", "SupeRX General Store", "Coca-Cola Presents The Salt Water Circus", the "Firestone Airshow", a giant "Gillette Mach 3" ad in the queue for Top Gun, "Paramount's Kings Island" The difference between the ads we see today and the ads from 1972-1999 is both that Cedar Fair chose to not display many in their parks (leading to a mostly ad-free experience), and that the ads of yesteryear were presented in a somewhat more elegant manner. 

This seems to only be in effect for Legacy Six Flags parks. I can't find a similar message on Kings Island's Pass Perks website, which leads me to believe that this is part of the Cedar Fair-ification of the new Six Flags.  Maybe we'll even be lucky enough to see the new app and websites come to life soon. As bad as the Cedar Fair apps might be, the Six Flags app is absolutely awful. I'll admit that some of the issues could be merger-related and others could be user error. Where it stands half of the park maps don't work properly, the attractions pages show out-of-date information, and there are some very noticeable bugs that make the experience very inconsistent. 

To be fair, it was done before the merger and under all other operators—it was always just always a bit more tasteful, clever, or creative. The example here is just a pure, lazy cash grab.
