This study intends to combine three theories to understand the adoption consumer behaviour to use information technology in travel and tourism activities. That theory is TAM, TPB and DIT. The amount of research that integrates these three theories is relatively small. The Respondents were tourism website users that active using the website in the last 3 months. The samples to be taken in this study were 242 people. Result showed that social influences have positive effect on perceived usefulness and perceived ease of use. Personal innovativeness has positive effect on perceived ease of use and perceived usefulness. Furthermore, perceived usefulness has positive effect on trust and behavioural intention. Ease of use has a positive effect on perceived usefulness and trust has negative effect on perceived risk. Ease of use doesn't have effect on behavioural intention and perceived risk was also doesn't have effect on behavioural intention.
