I'll sometimes swap out lands and attractions in concept plans, and in this case I imagined that a Pacific Islands themed port, based mostly on Moana, would be a fun alternative to the Mermaid Lagoon port that had been done once in Tokyo.
There are similarities with the previous port (Mermaid) in that there is a kiddie coaster (re-themed to a coconut grove) and a character-based spinner outside (re-themed to the pig and chicken from the film). And a large indoor space: I imagined a network of torch-lit caverns under the mountains (as seen in 'Moana', where she discovers the ancestors' canoes) that houses some retail, dining, restrooms, etc. There is also a major attraction found in the caverns: an outrigger canoe simulator (mini-domes) with water-effects that take riders across the wild ocean to mythic locales.
Built atop of the cavern amid the lush peaks of Motunui (and Hong Kong) is a rapids ride. A waterfront-dining venue based on the chief's huts rounds out the features of this port.
The former Peter Pan Mermaid ride becomes a Peter Pan Pirate ride and joins the port of Buccaneer Bay
