Travel with cruise ship (cruising) is a luxury type of nautical tourism that has been growing more and more recently and is becoming more accessible to the masses. Cruisers carrying passengers from port to port are becoming bigger and can accommodate thousands of passengers at once. In some ways they are becoming like mini-cities on the sea. This type of tourism and travel in the 21st century has grown and more people can afford to go cruising on mega cruisers sail around the world. In the last fifteen years, Croatia has experienced an increase in cruise tourism and has been developing a strategy for nautical tourism in general and cruise lines in particular. Although, according to statistics, there is some stagnation, if not a decline in travel, the number of arriving passengers is increasing. The arrival of such a large number of travelers to the destination certainly has its positive and negative sides, especially for prefferd destinations in the Adriatic, Dubrovnik in particular. Cruising passengers from a single cruiser can completely disrupt traffic and endanger the general safety of citizens. The advantages and disadvantages of cruise tourism certainly exist and both sides are significant. Profitability, economic effects for islands and technology development, renewal of moorings and anchorages are all features that should not be ignored, but should systematically and strategically consider all the negative effects such as over-commercialization, environmental destruction, and the like. Crucial to sustainable development is cruise tourism, focused on strategic features that emphasize the ecology and conservation of natural beauty and the desirability of the destination.
