A few years ago I was working in BKK and rented house in Cha Am for the weekends...ie I have done that route many times by bus, minibus and train ... but by all means take Fishtaco's advice if you want Jaxw.

OK I'm outta here... but before I go I'd say you'd be best taking a taxi jaxw.... about 2000B as Shanek says.
