I think this is a minibus route, not a bus route. The only buses go from BKK to Chantaburi (not calling at Pattaya) so you'd need to wait for the bus on Sukhumvit road, which is a fair distance from the middle of Pattaya. Not sure where you'd catch the minibus from, probably the van company's office, wherever that is.
Sorry I misread, Chantaburi to Pattaya not the other way around. Vans will leave Chantaburi from the bus station there and go straight to Pattaya.
Thanks for the reply.
