Leisure services are integral to the tourism industry, shaping traveler experiences, and impacting regional economies. Understanding the determinants of leisure service development and trends is crucial for stakeholders to adapt and thrive in a dynamic market. Leisure services directly impact tourism stakeholders, including businesses, policymakers, and destination managers. Identifying factors influencing trends is essential for sustainable development and enhancing visitor experiences. Despite their significance, existing research lacks a holistic analysis of leisure service determinants and regional dynamics. The research presented analyzes leisure service structures and investigates factors determining trends in the tourism industry in the European Union. It addresses key determinants and regional disparities in leisure service consumption. Using a mixed-method approach, this research blends quantitative and qualitative methodologies. Data collection involves literature analysis and application of economic theories, tourism demand, and consumer behavior theory. Quantitative methods include descriptive statistics, cluster analysis, and correlation analysis, alongside qualitative methods such as analysis, synthesis, and deduction. The research aims to bridge gaps in cross-cultural and cross-regional leisure service studies, providing insights for informed decision-making and sustainable tourism development.
