I got an offer from HHV for their Waikoloa Village (near Kona) for 6 nights, 7 days, full size rental car, $200 in Hilton gift certificates for future hotel stays, luau for 2 all for $999. I took the bait (though it took a while for all of the goodies to be offered).
What's interesting is that my wife and I did an HHV discounted stay at this same property several years ago. Quite a database they have.
