I have. And I maxed the shit out of it. Whatcha want to know?
Edit: Here are some more specific questions that will help me help you.
1. Where are you staying (which island, what part of said island)?
2. What is your free time schedule like?
3. What do you want to know about - food, hikes, touristy shit? Must Do stuf? Travel tips specific to HK?
Seriously. I am here to answer all your questions. I knocked HK out of the park last year.
1) Mandarin Oriental Hong Kong
2) Free time Saturday and Sunday
3) Food and must do stuff - I hear Macau is pretty nuts.
