Don't be dumb!
Why was all the time for saving les than 500 Baht. Yepm you go all the wat to Heaven and blow it! Right after you go past the baggage check ( such as it is) and out to the Arrivals hall go to the AOT Limo desk..... About 1 min and you driver will be pushing you cart to his waiting car and off you go. Taxi, plus tolls etc.. FaGetAboutIt as thehy say. Don't waste you time..... I know a guy who wouldn't pay fopr the tolls and took t hours to some dump on Soi Nana!
