Tourism, holidaymaking and travel are these days more significant social phenomena than most commentators have considered. On the face of it there could not be a more trivial subject for a book. And indeed since social scientists have had considerable difficulty explaining weightier topics, such as work or politics, it might be thought that they would have great difficulties in accounting for more trivial phenomena such as holidaymaking. However, there are interesting parallels with the study of deviance. This involves the investigation of bizarre and idiosyncratic social practices which happen to be defined as deviant in some societies but not necessarily in others. The assumption is that the investigation of deviance can reveal interesting and significant aspects of normal societies. It could be said that a similar analysis can be applied to tourism.
