The aim of this study is to compare the Baltic States (Estonia, Latvia, and Lithuania) and Hungary’s economic and social terms in the period from 2004 to 2015, with an emphasized character in the tourism processes. Each of the four countries joined to the European Union (2004). The 2008 economic crisis seriously affected these areas at both national and regional levels. We try to find the answer to what kind of processes took place in the economy and in tourism; and what kind of role has the regional marketing toolbar in each countries’ prosperity; and it is still possible to enhance the affirmation of the tourism potential with the online marketing tools.
