Thanks very much for the helpful, unsarcastic responses. Clearly we have not been to hong kong before or else I wouldn't be asking for help on this website!
and yes, we have already planned to get a serviced apartment to give us a chance to look around, but great to get other more experienced people's opinions on various areas to consider living longer term and check that my research is not far off the mark.
Thanks again. Im sure you'll see my many ignorant questions popping up over the next few months! including considering bringing my cat! i know i know - many people think i am insane - but i have read some positive stuff on the pet forum threads! we'll see.
I am arriving in August so still have time to plan and consider.
