Agree it is just about enough time to do it without rushing...but would only recommend for someone who knows HK reasonably well and knows exactly what they want/ where to go. Otherwise, it's a) a bit of pot-luck what you are going to get and b) a little too stressful/ and too late to appreciate much of the environs except the harbour if one ventures that way.

Since they OP is going to get into the Wing...the food is pretty decent there, and I would say it's worth at least one visit. Leave HK to a proper stay.
