That's how I hope it is, very subtle. Almost how most of Tomorrowland and Epcot attractions used to have sponsorships in the past, I'm hoping Moana is just sponsor that's quite irrelevant to the whole experience itself. Mostly there as a name, which is nothing new to Disney.And...
This addition to the park isn't really a Moana feature anyway.
It's more an "inspired by Moana," or a Moana branded feature.
