I have never been to that property but have always had water straight from the tap in HK at the properties I have stayed at. Conrad, Prudential, Sheraton, Holiday Inn and Royal Pacific are the ones that come to mind immediately but probably a couple I dont remember. I think the deal is.....the tourism board and hotel have to give safe answers. They tell you it is fine to drink and then you get sick or something (even if it is not the water) then they have to deal with liability.

I am sure there are areas that you should not drink the water but I have not had any problems at the hotels I have been to.
