‘Models are servants, not masters’ (Clayton & Radcliffe, 1996, p. 211). Although the TSAMs (the BTS and ATSI) provide very useful information in understanding the system quality of a tourist destination, the information should be used not as an absolute solution, but as a reference. In addition to the intrinsic limitations of quantitative data (see Ko, 2001), there are a number of issues in the destination which cannot be explained by quantitative data. The wisdom and experience of stakeholders might be more valuable than these statistical data to cope with their issues.
