The use of self-reply questionnaires as a data collection instrument is common intourism research. However, while there is a long tradition of use of these instruments in social science research, there has been little discussion of the particular needs and challenges created by tourism situations. This paper blends both theory, practical and experience to suggest a range of issues and guidelines which researchers may find useful in preparing a selfreply questionnaire. A number of technical issues associated with surveys are also addressed. A number of principles and examples of good practice from the literature on survey methods and survey design together with the problems of using this positivist mode of data collection in tourism scenarios are developed.
