Social media is not real life. A quick perusal of park-centric "social media" would have me believe that literally every ride at every park is closed for several hours every day, and when not closed, almost killed their father's, brother's, nephew's, cousin's, former roommate due to a restraint malfunction, etc. It's all meaningless nonsense propelled by algorithms designed to trigger outrage.
As pointed out above, the only thing that matters is whether the parks are still pulling in revenue on Saturdays in October. And there has been absolutely zero indication that the parks will have any difficulty doing so.
I agree that the messaging strategy regarding now up-charging for certain attractions was poor. But the fact of the matter is that it has never been cheaper, in my lifetime at least, to visit the parks. If anyone is so so price-sensitive that they're going to complain about the value proposition, previous fall attendance trends suggest that there are literally thousands of others who will happily take their place, ready to pay extra for access to haunted houses.
