I just came from the Hilton Hawaiian Village a couple of weeks ago. There is indeed a Grand Vacations Club on the property (the Lagoon Tower). They were offering 20,000 points (down from 30,000, I'm told) if you attended their presentation, plus 100,000 more points if you signed up for the offer.
As for "timeshare runs," sorry, you're only eligible for points every 12 months. The Grand Vacations Club website (hgvc.com) has more details on current offers.
