Confirmed upgrade on booking. I never use the spa credits, don't care about tea, sometimes use F&B credit, but given the restaurant choices in Hong Kong it would not entice me. ( and theirs are not on my list of favorites). What would entice me would be confirmed upgrade on booking and one way airport transfer on arrival with jetway meet as can be ordered through the airport or hotels. That would be an enticing combination,even though I normally prefer staying on Hong Kong island at Four Seasons due to the location. This could sway me.
