I just called and spoke to an employee at Darien Lake. They said they have cancelled Dark Waters???? It is now going to be Family Fall Fun, with no haunted event. But, it you buy a ticket at Topps Market, the price of admission is only $19.99.
I Googled Dark Waters at Darien Lake. The total of the extra fee for the Halloween attractions will be $10, if you go to all of them. They are reducing the park admission to $19.99, if you buy tickets in advance. When I called to find out what rides would be closed during Dark Waters, they didn't have the information yet.
