The old claim "There is no prostitution in Thailand" is wearing a bit thin. That coupled with entry tax on top of departure tax and the threat of foreign income tax on anyone who stays longer than six months in a year does harm to all tourisism. If you add tour bus crashes, ferry sinkings, taxi scams, general rip offs and double pricing at government parks it's Amazing there are still any tourists.
I love all the predicted income forecasts we get from the various tourist comittees, do they throw dice to decide how may billions the latest brainwave will make.
