one person?
taxi is reasonable, pending traffic timing
you can also take train to station w/free transfers to hotels on Nathan
avoid the transfer bus which is shared with many stops on the way (there is a kiosk near the exit area) You also get your Oyster Card there (HK$ only?)
There are several really good links at tripadvisor.com to show all the details of options.

Nathan Road--night market, bird market, so many restaurants (mind the electronics/watch folks there)
Star Ferry, Kowloon riverfront, HK Island, so much to do--so little time!
