This research explored the connection between the quality of service and the customers of high-tech hotel chains located in China's top cities. The investigation focused primarily on the effects advanced technology integration—the kind involving artificial intelligence (AI), robotics, and mobile apps—had had on customer confidence, contentment, and loyalty. Through a quantitative research approach, questionnaire data were collected from 1,200 participants located in principal cities such as Beijing, Shanghai, Guangzhou, and Shenzhen. Descriptive statistics, correlational, and regression statistical methods were used for the analysis of the data by revealing substantial trends in the behaviour of consumers. The research shed light on the central role played by the quality of service in melding the perceptions and behavioural consequences of consumers. Those hotels that had successfully merged technology-based innovations with time-tested aspects of reliability, empathy, and responsiveness achieved higher customer satisfaction and confidence. The resultant psychological states were found to mediate the relationship between the service quality and loyalty towards the brands, as evidenced by the heightened intentions to come back, favourable word-of-mouth, and long-run loyalty towards hotel brands. Young consumers with a technological bent favoured advanced technological functions, whereas elderly consumers valued the aspect of reliability and customized human interaction. The research deduced the need for smart hotels to achieve a balance between technological effectiveness and customized provision of amenities. The research reinforced the importance of establishing the trust of consumers based on reliable mechanisms, data protection, and humanified provision of amenities. The findings had valuable implications for hotel administrators and planning policymakers for increasing the competitiveness of the fast-changing hospitality segment of China's leading cities. .
