Have you been and stayed at sapphire falls? I have- and I don't see how it's any less themed than the Polynesian, beach and yacht club, Saratoga springs, old key west, contemporary, coranado springs, etc.
I mean, port orleans and sapphire falls are far more themed than any of those Disney deluxes.
Sapphire is legit. The bar area, the falls and river, the colors and shutters outdoors, etc etc etc.
it's as themed a moderate as you could hope for.
