HK airport to Ocean Park public transport

Does anyone have the low-down?

Also, any ideas for a one-day stopover with a six-year old (perhaps near the Ocean Park, which is in Aberdeen)?

Your best bet would be to take the train from the airport to Hong Kong Airport MRT Station. Walk over to the Star Ferry and buy the bus and park admission tickets from the little kiosk to the left of the Star ferry (as you were coming off the ferry) where the buses stop. Alternatively you can get the MRT over to the Admiralty bus station from the Hong Kong Airport MRT station and do the same.

OK, thanks for the advice!
