guys, thanks a lot for your advices. I am more incline to stay at the PH due to the feedback here and also partly on the location. I don't know what to expect as I was told hotels standard are different from what we have in Asia, so I have to wait and see.
lawyertalk, I didn't actually check the rates for the other chains as I would like to secure points for my goldpassport/marriot reward membership, but i checked that yesterday and the others seems to have much higher rates than the PH & RC. I booked the RC a while back using my employer's corp rate and it is fairly decent, but looks like I am going to drop it now...
