@Paul ******
Ban Laem and Ban Pakard in Chanthaburi Province are open from 9AM <- that's where the services from Pattaya and Bangkok bounce their people at
I don't pay any attention to the one at Aranyaprathet/Poipet as it's an armpit of a border I wouldn't recommend EVER
Chong Chom / O Smach isn't bad though (as it's a slow border for foreigners)
