Airport Rail Station is Closed
When you arrive at Bangkok international Airport beware that there is a Rail Station under the Airport. The place usually looks like closed and sometimes is hard to understand how you go there. One time I was walking and a guy told me that that the Rail Station was closed and offer me a taxi to my Hotel for 900 bath. I was a little bit suspicious and I kept walking around until I find the machines that sell tickets. (these machines can be hard to notice). I end up paying 70 bath to go home.
