The development of smart tourism, which is based on the application of smart solutions in the tourism sector, is becoming increasingly important in the European Union and the Republic of Croatia. This thesis explores the application of smart technologies in tourist cities. The analysis reveals that smart solutions significantly enhance infrastructure and quality of life in tourist destinations, enabling better travel planning and resource management. A key success factor is the collaboration between the private and public sectors, ensuring efficiency and innovation in the implementation of smart technologies. This thesis presents a comparative analysis of cities characterized by significant investments in the development of smart tourism destinations. Additionally, a case study analysis has been conducted on the examples of Dubrovnik and Rovinj. The theoretical and empirical analysis highlights the need for further investments in smart solutions, better sector integration, and continuous monitoring of tourism trends to improve tourism products and services.
