Geographical location and accessibility. Thailand is located in the heart of Southeast Asia. This geographical location enables the country to be a natural gateway to Indochina and Southern China (TAT, 2001). Thailand’s geographical advantage as a major hub for Asian air traffic makes the country easily accessible by tourists and it has become a natural center for air traffic. The access to coaches, buses, trains, taxies and airplanes that have flexible schedules makes traveling in the country convenient.
