The primary aim of CRC Tourism’s research report series is technology transfer. The reports are targeted toward both industry and government users and tourism researchers. The content of this technical report series primarily focuses on applications, but may also advance research methodology and tourism theory. The report series titles relate to CRC Tourism’s research program areas. All research reports are peer reviewed by at least two external reviewers.
