I still think a flat ride package is a strong possibility over the next 3-4 years. Having an mini themed area that ties to the larger themed section of the park it sets in. (Ex. Use part of the Dinosaur's Alive area for a "Country Fair" themed setting for the flat ride package. That mini theme area would fit perfectly in the Old Va section). Whether or not a flat ride package would go in the revamped Jungle X-pedition section, I am not sure.
It would have a couple family oriented flat rides, a couple thrill oriented flat rides, and maybe one "signature" flat like a Disko coaster style ride (the large version with the "hump" in the middle of the track).
KD is down 3-4 flat rides overall compared to the early years of the park. So, a flat ride package is high on the list of future attraction possibilities. My cost estimate is 12-15 million for something like this.
I'm personally not so fixated on another coaster being built on Volcano's former site. That piece of land held an attraction complex that put KD on the map for regional theme parks for over 16-18 years and it was NOT Volcano. It was "The Lost World" mountain complex.
CF and KD management have been focused over the last 7-8 years on the parks past and bringing back common theming elements to tie each section of the park back together again. Many times providing new rides and attractions with a nod to the park's past.
At this point and time, I do not rule out any possibility for that area (coaster, flat ride package, dark ride). And, whatever is going in that area, we are not going to know until almost a year to 2 years from now. The sky is the limit at this point.
