This paper explores the specifics of applying benchmarking tools in tourism, with a focus on Croatia and Slovenia. Benchmarking tools provide tourism entities with a means to compare key performance indicators with competitors, enabling improvements in operational efficiency, service quality, and sustainability. The theoretical framework outlines the development, types, and applications of these tools across various industries, with a particular focus on tourism. Empirical research includes both quantitative and qualitative analyses, pinpointing the challenges and opportunities that benchmarking introduces to tourism organizations. Comparative analysis highlights distinct approaches in Croatia and Slovenia: Slovenia prioritizes sustainability, leveraging practices in eco-tourism and community engagement, while Croatia focuses on enhancing operational efficiency and adapting seasonal tourism to reduce its impact. The paper provides recommendations for tailoring benchmarking tools to meet the specific needs of tourism entities in these regions, alongside guidelines for continued research to address evolving industry demands and trends.
