The theme of this final work is the marketing and financial aspect of the operational management process of “The Sun” hotel, and the motivation for choosing a topic is the result of a long-standing practice of the author in a hotel company. The fact that modern tourism is a dynamic and heterogeneous business that constantly follows global trends is a true challenge to every hotel company, as well as for the hotel company of “The Sun”. There are numerous factors in a tourism market to keep track of all the changes, so hotel companies deal with them accordingly. Changes must be effective and immediate and include all departments and sectors of the hotel to get visible results. Nowadays it is almost a rule that hotels neglect traditional forms of business and introduce new modernized forms adapted to current trends in the tourism market. In modern business, hotels cannot meet the requirements of all segments of demand, instead they are focused exclusively on individuals, constantly working on specialization. The purpose of this work is to demonstrate the marketing and financial activities of “The Sun” hotel, problems that “The Sun” hotel faces, especially as a result of insufficient investment in infrastructure, personnel and innovations, and ways to solve the problems. In the development process, various sources of information were used, mostly examples of the author’s practice, Internet sources and professional literature. As it can be seen from the title of the work, the practice of a particular hotel is presented, and given examples are taken mainly from its business.
