This study empirically tests the capacity of Davis’s Technology Acceptance Model (TAM) (Davis, 1989) and Davis et al.’s Motivational Model (MM) (Davis et al., 1992) to help understand the determinants of the intention to use the internet to search for holiday information. The findings show that these theories do explain the intention of internet use by the tourist. Keywords: internet marketing; tourism information; Technology Acceptance Model; TAM; Motivational Model; MM.
