The hotel confirmed there was an airport shuttle at the time of my arrival (2am). But the transportation office at the airport said there was no shuttle at that hour. So I got a taxi for 300 thb. I did not ask the hotel what happened.
Very helpful staff and location is very convenient to walk for food or drink. They have an open air restaurant which is nice.
