My inlaws also own at Kauai Beach Club. I understand from them that the maintenance fees are indeed lower for 2012. KBC owners have been getting gouged for years now, so the relief must feel especially good.
One reason for the decrease may be related to the many KBC owners defaulting on payment of maintenance fees. I wonder if the realization has finally set in that there is a eventual breaking point if the fees go too high. Just look at the non-stop stream of KBC resales on eBay going for very low prices. The last thing that the KBC board wants to see at this point is even more owner defaults. Otherwise the whole house of cards could come crashing down.
