2) Time Saving and waiting between flight & Train (Total Travelling Time)
3) Flexibility / Comfortablity for family with children
is it consider international flight travelling from Guangzhou to Hong Kong (I meant you have to be in the airport 3 hours before flight departure or 2 hours?). Or if by train how far is from Guangzhou to Hong Kong and how long time spend for passport check in the boarder, etc... until you arrive center of Hong Kong?
My concern about travelling time as the distance KM between Guangzhou and Hong Kong is not so much.
I would like to know from your experience for those who are in the forum
