Institutionalization is a process that requires adaptation and alignment with the environment, ensuring stability and value in the organizations. The tourism sector holds significant importance in the economic growth of all countries. As a result, institutionalization is considered a critical management approach for tourism businesses to navigate competitive market conditions, maintain profitability, and sustain their market presence. This research aimed to evaluate the perceived level of institutionalization among 368 employees from 50 five-star hotels in Antalya. The study employed descriptive statistics along with factor analysis, t-tests, and ANOVA tests. The findings showed that employees' perceptions of formalization, cultural power, professionalization, and consistency differed depending on factors such as the total workforce size, bed capacity, and the operational duration of the hotels where they worked.
