I will just add to the advice that you have previously been given. Rescind now while you have the chance. After that is complete, then you can further research. You can always buy this same offer from the developer again but I am sure that resales will be a much wizer choice.
Thanks for the reminder GT75. I have every intention to rescind the offer, as I'm still in Hawaii (vacationing) and can walk over to the sales office to submit the pre-printed "notice of mutual right of cancellation of time share purchase". Apparently, HGVC has a good reputation of cancelling within the 7-day window and they seem to have a pretty strong process in place to make sure it goes smoothly. Looking forward to figuring out how to best spend my money wisely. Thanks CalGalTraveler, fillde, frank808, csodjd, alwysonvac, Cyberc and GT75 for helping me out on making this decision. Hopefully, no HGVC rep is listening in on this conversation and tries to persuade me to not rescind.
... as a side note, a funny story was that when visiting the local stadium swap meet and we decided to purchase what was thought to be a discounted luau, but it turned out to be yet another travel membership club. Ended up sucking up a few hours of our time. We must be a magnet for these things. Apparently there is not such thing as a great deal here in Hawaii without a catch.
