We've bought a few of these "preview packages" from SVO and Marriott (at other resorts) and have never received stay credit or night credits. The excuse we were given is that the rate is not eligible even though it was booked through SVO or Marriott respectively.

I always hold it against them - asking for a $50k investment but being chitzy about something that costs you nothing. Doesn't speak well for the programme. YMMV.

Have fond memories of this property when I stayed here a decade ago during its prior incarnation as the Hanalei Bay hotel - will be interesting to see if SVO has done much in the way of upgrades. Like many we are debating St. Regis v. timeshares, but leaning towards the former since we aren't bringing the kids.
