The quick placement of guest self-service kiosks in hotels has created a need to understand better how to motivate guests to use the technology. This study extends the technology acceptance model to explore the effects of social influence and perceived enjoyment of customers' acceptance intention of self-service technology in the restaurant industry. An online survey of hotel guests shows that social influence and perceived enjoyment can significantly increase guests' perceived usefulness and acceptance of self-service kiosks, while social influence increases acceptance. This paper offers theoretical and practical implementations for operators looking to increase customer acceptance of hotel self-service kiosks.
