The Kaohsiung Marriott Hotel was situated in the prime location of North Kaohsiung, serving as a local landmark with its modern ambiance and captivating scenery. The nearby Aozidi Forest Park further enhances its position as an urban backyard. However, in the fiercely competitive hotel market, consolidating its leading position and continually enhancing customer satisfaction prove to be a highly challenging task. This study employed a convenient sampling survey method, focusing on five restaurants within the Kaohsiung Marriott Hotel. These include the Meixiangdi Restaurant on the eleventh floor, Xiang Le Japanese Cuisine, the Royal Gourmet Steakhouse Teppanyaki, as well as the Haoxiang Buffet Restaurant on the ninth floor and the Jingsui Hong Kong-style Dim Sum on the eighth floor. Through the questionnaire survey of consumers at these five restaurants, each restaurant completed seventy surveys, resulting in a total of 327 valid surveys, for an impressive 93.43% response rate. Data analysis employed the Partial Least Squares method using Smart-PLS4 statistical software to analyze the structural model of the impact of Kaohsiung Marriott Hotel's brand personality on customer satisfaction, assessing both the reliability of the model and the study hypotheses. The research findings confirm a positive and significant impact of brand personality on customer satisfaction. Brand personality, as a distinctive trait of the brand, plays a crucial role in shaping consumers' overall impressions and attitudes toward the Marriott Hotel. By establishing a quantitative model of brand personality and customer satisfaction, this study provides a comprehensive reference to understand the impact of brand management on enhancing customer satisfaction for formulating more effective brand management strategies.
