I did notice that when doing a search on the IHG site that the Silom hotel does not show up but the hotels direct link seems to work ok, http://www.ihg.com/holidayinn/hotels...th/hoteldetail

I would venture to say that it is either a web site problem or some writing on the wall. I would not be surprised if they aren't being affected negatively with all the new HI and HIX properties coming online in BKK.
