I started early in hoping to be able to catch 6:45 am bus from Ekamai station. But it turn out that the earliest bus is at 7:45 am. Oh well,  so I should have slept in a bit more. So I grab some pork floss bread from 7-11, and wait till the bus depart.
The bus is quite nice and cozy, it traveled to airport to pick up few more passengers,  then stop by Chon buri for refueling.
