I'd recommend you look at a few maps and get a sense of where the various districts are. In general terms no where is very far in HK. If you travel for more than an hour you have either been stuck in a lot of traffic or gone a long way! Public transport is cheap and taxi's are inexpensive.

If you want opinions on hotels you are going to need to let us know your budget. Given you want to stay over Xmas / New Year things are unlikely to be cheap.
