Driver seemed disorganized and took ages for us to leave the airport. Despite the flight being late to arrive he stopped to re fill the van with fuel. While this seems trivial, he then decided he needed to make up time to get to the ferry and drove quite erratic. I have visited Thailand many times and used a lot transport but this was the only time I have felt uncomfortable with a driver.
My experience was great. The driver was waiting for me at the airport. He was friendly and helpful. I was the only passenger so I had the van to myself.
