I stayed here a couple of weeks ago on free nights. I'm not a fan of the unannounced category change, but in their defense, the summer rates are eye-watering ($680 for the base room during my stay). It's certainly one of the best (and priciest) ICs I've stayed at (considering that IC GS HK and SIN price at 50k points, this place would be worth 150k). My problem wasn't so much the unannounced change, but the fact that for a periods of several months, there didn't seem to be any award availability at all.
