I just received noticed by mail that Aulani points are increasing this month. Last up the points were going for $150.. Now increasing by another $5. If you buy more, you save more. But I noticed that you can purchase from current owners for almost half price on the open market. You don't get the tradeability, buying direct DVC, but getting more bang for the buck is the name of the real estate game.

If you're needing studio, then purchase at Aulani. If you're staying one bedroom villa, then perhaps you can chance buying else where and booking Aulani.
