If you are trying to go to anywhere but Aulani, I would not buy Aulani.
I seriously considered a subsidized Aulani contract and decided against it because of Hawaii's laws and risk factors like taxation. Also, Aulani as a timeshare has a troubled history, and might never actually be sold out on Disney's end. I plan to sell, and I don't want to be selling that product.
At a minimum, you need to look into Hawaii's probate and property transfer laws. To me, that was a complete no go, and I wouldn't buy outside of FL.
