Is OP an RA? Ten years ago, the lounge cost over HK$800, Both IC in Hong Kong are known to be stingy regarding upgrade and lounge access. It is unlikely you will get anything more than required. When I stayed at IC GS in 2009, I was told by front desk that I have to choose between room upgrade and lounge access. She said that to me while looking at my IC RA membership card. I took the room upgrade.
