Tourist behaviour at chosen destinations is influenced by the information they may receive during their stay. Many decisions, such as visiting attractions, events, car rental, booking restaurant services, prolonging their holiday stays, etc., are made during their stay, with increased booking of activities leading to higher revenues for the destinations. The information-behaviour interaction also creates a mind-set in tourists that combines experiences, emotions, prior image of the place and satisfaction, which favours tourists' predisposition to return to the destinations and recommend them to friends and relatives. This paper proposes a theoretical model relating the effects derived from efficient information at tourism destinations. The model can help researchers, tourism marketers and managers at Destination Management Organisations (DMOs), Visitor & Convention Bureaus (VCBs) and Visitor Information Centres (VICs) understand the beneficial effects of efficient information at tourism destinations.
