But I think the thought is they will escalate faster like Hilton head and vero because it is beach front. Those are significantly higher than the rest of dvc.
I don't think you can accurately compare Aulani to either Vero Beach or Hilton Head.
The Hawaiian Islands get hit with significant storms maybe once in 25 or 30 years (the last being Hurricane Iniki in 1992). Because of the general weather patterns in the north eastern Pacific, there are barely a handful of storms (fingers on one hand) every year that could even generate significant damage and then you have to have the perfect storm pattern to even get close to Hawaii. The East Coast, on the other hand, has 4 or 5 times that number, in an area 1/4 the size. The chances (and history) of Vero and HHI getting hit by either a hurricane or strong tropical storm are much, much higher.
An extreme example would be if Disney had decided to build a resort here in the other Orange County, next to the Ritz Carlton in Laguna Niguel, for example. While not a "desert", we are considered a "semi-arid" climate, with minimal rainfall and typically very dry (low humidity). That hypothetical resort, built right on the beach, would get virtually zero effect from or exposure to, storm damage of any kind whatsoever. It's all a matter of degrees.
Also, the construction types are radically different, with Aulani primarily a mid-rise concrete and steel structure with engineered exterior curtain walls. Yes, there is the constant presence of moisture, but the buildings are newer, better designed, and incorporate better construction technology.
