The cost of a day pass for a family of four is now $85. We stayed at the Kohola Suites but asked at the hotel's front desk just to see how much it costed.
BTW, we ended up going to the Hilton twice. For the number of points, 9600 for the two bedroom penthouses, I'm strongly leaning toward going to the Villas at the Bayclub (8400 points for a week) and paying the $170 the next time we go. This is because the Villas are bigger, have the same view with much bigger Lanais and cost 800 points less. The Koloha Suites are newer, have the Plasma TV and upgraded cabinets but I think the Villas is nicer.
