Thanks guys.
Not Cx or KA but HKE so would make the trip a lot more frequently. I think 1.5 hrs is a bit much regularly, so maybe DB is best option?
SMOC - you don't like DB?
Maybe Mui O is an option? What's the transport like between Mui O and DB if my kids school there?
Or is it feasible to drive from Sai Kung to somewhere cheap to park and take a bus/MTR from there, to cut down the journey time?
Thanks again for the help.
