I don't think your comparison is fair. A fixed cost like closing costs, on every new contract, is far different from a limited time incentive program that is clearly designed to be offered for a specific time period and then disappear. I don't think anyone would go back and say they deserved an incentive that had expired two weeks before they purchased - most people know that incentives come and go. But closing costs that have never been reduced or waived for a single buyer are different, and I think if someone did manage to get them waived, all of the other buyers who heard about it would be within their rights to go back and try to get a refund of their closing costs. Just my opinion, of course - it's what I would do in that situation.
It seems to me that
DVC sales are strong - I think I recently read that SSR is 90% sold out, and AKV seems to be selling well. As far as the developer points, isn't there some sort of need to offer people something in order to get them to buy units that aren't even available to be booked yet? I thought that was the purpose of the developer points deal, but maybe I'm mistaken. At any rate, I don't think DVC has seen much of a slowdown, if at all. Kingdom Towers will sell out quickly, I believe, and the California property is so small I think it will sell well, too. I don't know about Hawaii.
It's fine to disagree - but your opinion isn't any more "right" than mine is.
