If you are there on a Sunday go fo r a Sunday Brunch.
Check on the best brunches there. I think it is the marriot but there are others that are booked up quickly. Amazing experience of gorging on food and booze.
The ferry is cheap, worth a ride. Hihg tea at the ritz was a good laugh on kowloon and had a great view.
Dinsey was ok, the other park would have been excellent if I enjoyed rides.
Walking around CBD nice, I found HK island easy to navigate, and a pleasant place to be.
Market are so so, if you have been to an Asian market before you will be underwhelmed, if you have never been to one you will love it.
Botanical gardens were decent, never got on the vernicular railway,, but everybody said it was good.
It is spendy though, with the the three of us staying there inc our flights for 4 nights 5 days, on a cheap flight from Mongolia, our daily cost was about 600 per day. We could have eaten cheaper, but we chose to enjoy ourselves, considering we were heading back to the cold and pollution.
