Welcome to FlyerTalk.
FYI, there is a forum in the FT Travel section dedicated to travel questions for Hawai`i. You might want to take a look over there and see if you can find the information you are looking for.
This forum is dedicated to Hilton properties only, so your responses might be a bit limited (although it appears many here have stayed at the HWV/HHV at one time or another)
Hope this helps.
ALOHA!
