But, that's the point. Manby has said they aren't trying to compete in the marketplace anymore. They are going for the local market and if they happen to get vacationers, so be it.
Also, having been to SeaWorld Ohio and SeaWorld Orlando, I can tell you the two parks were night and day. SW Orlando is a full fledged theme park with some great attractions, where as SW Ohio was a glorified aquarium. Also, BGT really is a top notch regional theme park, far beyond a Six Flags or Cedar Fair. To dismiss these parks for having attractions similar to your regional park would be like dismissing Universal for having similar roller coasters to them as well. Just because some attractions share similar designs, doesn't mean the parks have any similarities beyond that.
