That's a prominent rumor (with some evidence, I believe) - and one thing I would genuinely be excited about in a new project like this. Honestly, if this had more of a personality/perspective and wasn't directly in the Wilderness Lodge lake view, I think it would be a very nice project. Perhaps unnecessary right now - but nice.
A lazy river. And an interactive water play area. Plus a pool with a water slide and also a feature pool. And a lakeside table service restaurant, new boat dock, cabins along the lake and treehouses. If certain posters and rumors are to be believed.
