We will be staying at Disneyland for 3 nights in december 2010,what is the best way to travel from Disney to Kowloon and Hong Kong Island? Is it the MTR? If so, and we go out at night what time does the MTR close? How long is the MTR journey from disney to:
KOWLOON(MONG KOK,HARBOUR CITY)
hong kong island(causeway bay, THE PEAK, CENTRAL)

Also, am travelling with a baby - what is the weather like in mid december.Any help is appreciated, many thanks.
