Arriving on an early CX flight into HKIA at approx. 6:00am. Final destination is Dongguan. I typically would take the SkyPier ferry to Humen, however according the schedule, it appears I would have to wait almost 5 hours for the first ferry. Any other recommendations (ferry or overland)?
Hopefully someone has a better suggestion than I do but would it be possible for you to get to Hung Hom Station on the A21 bus and then catch a train to Dongguan? The link to the train timetables is
