I would think CF could do a land lease with a MGM, Caesars, etc. to get a hotel and casino built on site with associated restaurants, stores, and conference centers. CF could then build/operate an indoor water park to complement the hotel/casino.Indoor water park, maybe - I think CF has ownership in a small one of those on the road into CP.
Casinos have actually been legalized as of the last regular general assembly session, but will probably be a few years until any are open - only 5 localities can have a singular casino in them with Richmond being the closest. IMO though, I don't think CF would want that as it'd divert attention from the park and probably draw a different demographic than they're aiming for. Also, if they're not fully operating it they'd probably not get too much revenue out of the deal.
Getting a resort on site completely changes the dynamics of what KD is since it can become part of a multi-day trip and vacation packages the way BGW is in Williamsburg and Hershey Park is with the amenities around it. This makes CF's land a lot more valuable and desirable for further projects in the area.
