Anyway, Fright Fest was nothing compared to HHN or anything else. By the way, do you have to pay to get into the houses at HHN? You do at Six Flags!
For me, the idea of "ultimate Halloween event" has always been associated with the words "The Haunt". I haven't been to any of the non-Knott's Cedar Fair events, but if you're just asking for brand name power - I'm kind of surprised the Haunt is doing poorly in the voting. But perhaps there are a lot of east coast votes!
Seriously though...Cedar Fair's Halloween events (at least in Ohio) have gotten a lot better over the years. The only drawback to them now is that they are a heck of a lot more crowded than they used to be. Cedar Fair also inherits Kings Island's old Fearfest event, which was a good one to begin with. Seems they are a little edgier these days as well.
Year after year Busch continues to provide quality entertainment and atmosphere. The park is beautiful all the time, and the Halloween theme does not mar the beauty, but incorporates it into the settings. Busch seems to have a knack for hiring excellent people, as well. We will keep going back several times as long as they continue to do what they do!
