I feel like things got flip-flopped. A new Soak City ride came out and Rivertown got renovated. Next year, a Rivertown ride is being added and Soak City is being renovated. While it was to move things like Funnel Cakes and White Water Canyon's entrance for the new ride, none the less it feels flip-flopped and in a way ironic.
I can't imagine the smokehouse being that big. Thing is, it's a water park, therefore they have to make an environment that can get wet. I don't see it having too much indoor seating.
As for where it's going to be, your guess is as good as mine. My thoughts were across from the Coconut Cove Cafe because there's this sizable field there and already a lot of patio area. The other possibility is behind Tropical Plunge.
