The tourism sector, one of the most important global industries, has witnessed significant digital transformation over the past few years. Digitalization in tourism facilitates better customer engagement, improves operational efficiency, and enhances service delivery. However, measuring the level of digitalization in the sector remains a challenge due to the lack of standardized methodologies and indicators. This paper highlights the importance of digital infrastructure indicators in developing a robust methodology to assess the level of digitalization in the tourism sector. By focusing on key digital infrastructure components such as connectivity, digital platforms, and technology adoption, the paper proposes an integrated framework that can guide both researchers and practitioners in assessing digital maturity within tourism organizations. The paper concludes by discussing the implications of digitalization for the tourism industry and the potential for future research in this area.
