Cruise is a round trip by boat that includes a tour of several destinations. The ship serves as a means of transport and as a hotel. Today cruises are one of the most popular forms of tourism with a growing trend of popularity. Cruise tourism is a new, selective form of tourism that grew in the twentieth century, and has the peak in the last decade of last century. Cruising is mostly developed in countries rich in water (sea, rivers, lakes). Cruise tourism requires large investment funds and is therefore not always worthwhile with real investment and the right development direction ensures great profit through the future. This implies large ports, accompanying facilities in ports and destinations that have a carring capacity for a high inflow of large numbers of tourists. In the world, cruising tourism is the most developed in the Caribbean, but there are other continents as well. In Croatia, Dubrovnik is a leading representative of Croatia and one of the leaders in the Mediterranean.
