Tourism as a tourist activity is growing rapidly each year, so the number of tourism employees, businesses and activities is also increasing. Accordingly, the number of accommodation capacities is increasing as well. Focus of this thesis is to analyze accommodation capacities in the Republic of Croatia. The materials and methods I used in writing this thesis are primarily professional literature on tourism and hotel management. Furthermore, I used literature from professional articles and teacher presentations to complete the whole story. Data on tourist traffic and accommodation capacity have been collected and come from the internal data of the tourist boards of several cities. The thesis begins with an introduction in which it is explained in more detail why three specific years were taken as examples. This is followed by a chapter that talks about tourism in the Republic of Croatia in general. Then the tourist demand in 2010, 2015 and 2019 is analyzed. Since the Adriatic counties are the carriers of Croatian tourism, an analysis of arrivals and overnight stays in these same counties was carried out. For those same years, the offer and demand for accommodation facilities were presented, and the topics of hotel management, their standards, and specially elaborated topics of hotels and camps were covered. Towards the end, we have the supply and demand of accommodation capacities, the advantages and disadvantages of the market picture of accommodation capacities and a comparative analysis of the observed years. At the end is the conclusion of the paper itself, in which I focused on the future of both tourism in the Republic of Croatia and the accommodation capacities themselves.
