This graduate thesis analyzes hotel operations after the COVID-19 pandemic, with a special emphasis on changes in business strategies, adaptation of operational processes and the impact on financial results. The pandemic has significantly shaken tourism, forcing hotels to urgently adapt to new conditions and challenges. The paper explores key aspects of this adaptation, including the application of new hygiene standards, the implementation of digital guest contact solutions, and changes in marketing strategies. Case analysis reveals how successful hotels have adapted and how the implemented strategies have influenced their resilience and competitiveness in the market. Through a thorough analysis of the company's external and internal environment, financial statements and financial indicators before and after the Covid19 pandemic, the goal is to understand how the pandemic affected the key aspects of Arena Hospitality Group's business, i.e. its profitability and competitiveness in the market. Special attention is paid to the comparison of financial results before and after the pandemic, as well as to the evaluation of the long-term consequences that will shape the future of the hotel industry. This paper provides insight into key trends and recommendations for future strategies aimed at ensuring long-term sustainability and success in a post-pandemic environment.
