I'm thinking of doing a day or overnight trip to Hua Hin/Cha Am during my visit to Bangkok. I've searched all around but cannot find an official bus timetable departing and arriving from Bangkok's Southern Bus Terminal.

Would anyone have this handy?
Also, what's the easiest way to get to the Southern Bus Terminal from the Westin considering the morning traffic conditions? Taxi or public transport?


One more thing... is there an Airport bus from the southern bus terminal?

tia for the help
