ENTourism has a major impact on national economies, attracting foreign tourist flows and, at the same time, generating income, helping to create new jobs and contributing to attracting foreign investment. This is a huge business that is growing and will continue to grow. One of the aims of tourism development is to attract as many foreign tourists as possible, therefore it is very important to analyze how the incoming tourist flows are changing and which markets the Baltic tourism sector should target. Many scientists have analysed trends in tourism development: Gartner (1996) analysed theories of tourism development, Noranha (1976), Butler (1980) and Turner (2003) analysed the stages of tourism development, Nordin (2003) analyzed the diversity of tourism sectors, Holloway (2006) explored ways for the government to play a role in tourism, Hall (2007) complemented tourism development by a new tradition of sustainable development, Lomine (2007) analyzed strategic political and economic planning and decision-making in the public and private sectors, Getz (1987, 2008) worked in tourism planning, etc.
