SQ319, I did not stay at the HIX Orchard. I stayed at the HI Orchard City Centre but went over to the HIX for "inspection"

since I had a reservation for a stay two weeks from now - which I decided to cancel based on my brief inspection. So I don't know which benefits they offer to Platinum / Ambassador members.
I did not notice the construction behind the Concorde hotel; our rooms were facing Cavenagh Rd, that may have helped.
