I like this map better. Scroll your cursor over each area for more detail.

Customs is after the baggage belts. Passport control is before.

There's an ATM near baggage belt 10 right next to a small duty free shop and a currency exchange booth. Others outside. The map above shows atm locations.

There is a limo counter just before you pass through customs and one right after you get past customs and into the terminal (AOT I believe).

Soowannapoom is the correct pronounciation.
