Business tourism encompasses a specific niche of tourism such as global and diplomatic meetings, meetings between superpowers, trade and economic negotiations, business fairs, conferences and conventions, and the number of these business meetings increases every year, which increases the capital of the area where they are held. The Republic of Croatia competes with other European countries when we talk about business tourism due to its geographical location, cultural and historical heritage, events, traditions and infrastructure. The Republic of Croatia is financially most dependent on tourism, and the biggest drawback of tourism is its seasonality. Business tourism here can raise the Republic of Croatia to a new level, because it does not depend on seasonality and allows the continental parts of Croatia not only a rich business and tourist offer, but also a season throughout the year when talking about business tourism. In the same way, business tourism can contribute to the arrival of new tourists who visited a business destination and wanted to visit it again in their free time because of its natural beauty, services, experiences and traditions. It is precisely on the basis of this tradition that the city of Opatija attracts numerous local and foreign organizers to choose it as a business destination. Opatija has more than 50 congress halls with over 900 seats, and has also won awards for the best business destination with a rich tradition. In this paper, a comprehensive analysis of business tourism was carried out with a focus on business tourism in the city of Opatija, where the basic hypothesis was set that reads, Opatija is a significant center of business tourism in Croatia, which offers unique advantages compared to other Croatian cities and is based on the analysis of hypotheses and confirmed, because Opatija stands out for its rich history, tradition, infrastructure, quality, geographical location and congress centers.
