Sorry to hear about the rain. I used to live on Oahu, and it's actually commonly windy at Ko Olina, but that isn't the rainy side of the island. We lived on the windward side, and had much more clouds and rain than the Waikiki area. Ko Olina shouldn't normally have too much rain.
Ko Olina is still fairly new (although in 1995 when we moved there, the Marriott hotel was already there, but under a different name). We stayed at the Marriott timeshare a couple of years ago with some friends that bought there - it was very nice!
I think the Disney resort should be very nice - they were also building a Ritz Carlton fractional ownership resort there also.
Ko Olina is second/third tier real estate (it's windy and hot due to it's location at the foot of a mountain bluff and lacks the wide, beautiful natural beaches found on the eastern end of Ohau). I would have much preferred it if DVC had looked into building a resort on Kauai, which is prettier than Ohau and still has top quality seafront land available. Marriott did that, and here's the beach that their time share members get to enjoy at Kalapaki in Kauai:
There is a high hill back aways but it seems so gradual I wouldn't think it would have that much effect? KoOlina is located on the dry side of Oahu so the weather Diane experienced is presumably not the norm.
