The increasing needs of recreations foster the rapid development of hostels in Taiwan for both its main-island and off-shore islands. The owners of hostels try to provide special, calm and comfortable environments for their guests. This research aimed to explore the keys to the successful operating among the 190 legal hostels in Tainan, Kaohsiung, and Pingtung. From February to April, 2010, totally 115 surveys (61%) out of 190 ones were available for analysis. Based on the successful cases, the researchers synthesized the feasible methods and sustained management models for operators and related further research.
