Miniature Golf for Walt Disney World's Polynesian Village

Aloha! Like any good Californian, I really like my tiki culture! So, you can imagine how excited I was when this piece of concept art for a miniature golf course ended up on my desk. Is this possibly for Typhoon Lagoon or maybe it was part of a plan once upon a time for an expansion of the Polynesian Village Resort at Walt Disney World. Looks like it would fit for something next to Trader Sam's Grog Grotto even. Does anyone know more?
