A major limitation of this study is the inclusion of relevant publications only from
selected journals. In this study, eight leading hospitality research journals were
included. Publications from other journals, particularly information-technologyoriented
publications such as Information Technology & Tourism, Information
Technology in Hospitality, and proceedings of the ENTER conferences, the world’s
largest annual event on tourism technology, were excluded. Moreover, this study
focuses only on the perspective of suppliers, and the perspective of consumers and
technological development are not examined. Hence, future studies should incorporate
these other aspects into the analysis. Also, it is suggested that research should go a
little further to compare these categories of studies in hospitality and tourism with
those in mainstream business in order to identify gaps in the research that need to be
filled regarding hospitality ICT.
