Thanks for question Ron. Right, as I understand it there is a separate bus to Rayong from Suvarnabhumi Airport. You need to take the shuttle bus from outside arrivals to the airport transportation centre. From there go to the inter-city counter and from there you can get a ticket to Rayong. As far as we know service is from 06000hrs to 2100hrs and will take a couple of hours.
Buses also leave for Rayong from Bangkok city, from Ekamai and Morchit bus stations. From here you can get a regular service throughout the day.
Other ways of getting from Bangkok to Rayong are car, either hire or taxi, or plane. But come on, really? Is that a journey that warrants a plane?? Expect taxi fare from Bangkok to Rayong to be in the region of 3,000 baht.
Hope that helps. [This was in response to a comment on a previous post]
I have taken the bus from Ekamai to Rayong many times and it is usually a smooth on time experience, which always surprises me given the usually heavy and slow moving truck and bus traffic.
Hmm, so no matter if you are going to Pattaya or Rayong (or anywhere) from S. airport, you need first to take the shuttle to the transportation center? Got it! Thanks.
Glad to be of help. Any new news will be shared here. Please help by spreading the word and also let us know how you get on with your trip.
Thanks
