Presidential Suite at the old Ritz Carlton in Hong Kong.
Was 17 at the time and traveling alone. Dad surprised me and booked me a room via FHR. Arrived late at night and after a lot of confusion they showed me to the then largest suite on Hong Kong Island.
Was a great property which I don't believe that the current Kowloon location will be able to match. Going to give it a try in December though but don't have very high hopes.
