If this does end up like the Swiss Family Treehouse... what's wrong with that? I'm kind of glad EPCOT is getting a walkthrough attraction akin to the treehouse. The park needs some diversity in its offerings. It's utilizing a space that more or less functioned as a "walkthrough" before, in a way that ensures longevity and could very well become a staple of the park in the same way that Swiss Family Treehouse is. The IP tie in is there, and not necessarily subtle, but the IP is not really the draw. I'm not saying 50 years from now Moana will be as obscure as Swiss Family Robinson, but I can certainly see Journey of Water adapting an identity of its own, separate from the movie. The attraction looks to be designed in a way that would make it very easy to retheme it to whatever Disney's next big water-centric IP will be (or even remove the IP altogether, albeit unlikely). The intrusion of IP here is no less disruptive than many of the original attraction sponsors of EPCOT Center.
