Count me in the group that's hoping for anything but Nickelodeon. The whole Nicktoons craze is a decade past its prime, which is evident w/ the Nicktoons ride being replaced. Spongebob's ratings have been falling the last couple years, and I don't really see much merch in the stores anymore.
I actually had an off-the-wall idea that actually would fit nicely in Kid zone. Between Curious George, Barney and Cat in the Hat, they have experience with attractions that have PBS connections and have a strong preschooler bent. What if they rethemed the area to one of the bigger PBS properties right now: Wild Kratts?
It's the new show from the Kratt Brothers (of Zaboomafoo fame) and is extremely popular bc it blends live animal fact segments w/ cartoon action segments reinforcing the animal facts. Look it up on YouTube to get the idea.
Anyways, the Feival play area could easily be rethemed to Wild Kratts, the Woody coaster could be based on their Peregrine Falcon "creature suit," the Animal Actors show only would need a new script and the Barney area could either be turned into a small dark ride or a mini zoo.
Sure, there are longevity questions, but no worse than what's already there (my son's never seen American Tale). Meanwhile, the Kratt brothers have been on TV w/ multiple shows for almost 20 years. I took my son down to one of their appearances two years ago and the place was absolutely packed.
