And here is a great video I found on YouTube showing the best way to get to Pattaya going on the Roong Reuang Co. bus to/from Suvarnabhumi Airport – from anywhere in Bangkok – just take the Skytrain to the airport then..
Airport-Pattaya Bus Service (Roong Reuang Co. Ltd.) provides direct transfer from Suvarnabhumi Airport to Jomtien and vice versa, with only 32 seats in each coach and an estimated travel time of approx. two hours. The company’s Jomtien office is located outside the Foodmart supermarket on Thappraya Road (opp. Pan Pan restaurant, just around the corner from Thepprasit Road).
The departure location at Suvarnabhumi Airport is on the 1st floor of the arrivals terminal (between gates 7 and 8).
Departure times 7h, 8h, 9h, 10h, 11h, 12h, 13h, 14h, 15h, 16h, 17h, 18h, 19h, 20h, (21h), (22h)
One-way fare is 134 Baht (January 2014). www.airportpattayabus.com
If your coming to Jomtien – get off at the Jomtien office – easy walk to Jomtien Complex.
