I am not sure that I understand what you are basing your conclusions or numbers on. Can you explain? I also really don't think that asking HGVC is a viable option for us.
Hilton is tend to excercise ROFR on the units in Honolulu which has less than 30 percent of current official selling price.
In order to find current official prices, you can always ask to HGVC or search internet. Some agent in Honolulu also has the list of current official selling prices. 99% of platinum units which has less than 25% of official selling price will be taken by Hilton.
HGVC is aggresively buying back property in Honolulu except for Grand Islander and Hokulani with decent prices.
If somebody want to sell the properties in Honolulu, you should ask Timeshare Hawaii to proceed buying back by Hilton before list as resale.
Since there is no new development in Waikiki now, HGVC is trying to fill their inventory in order to sell it to Japanese, Chinese and Korean at tripled price.
I believe that is reason why properties in Honolulu has unreasonably hugh price. The right of home week reservation is important in Waikiki because of competion to reserve the room.
I hope I have answered your question.
