Indonesia, a populous country, exhibits a significant population size. As per data from the Ministry of Home Affairs of the Republic of Indonesia via the Dukcapil Directorate General, the largest generation in Indonesia comprises Gen Z and Millennials. These two generations display various behavioral differences compared to preceding generations, particularly in their travel habits. In order to attain the national tourism target, the Ministry of Tourism and Creative Economy (Kemenparekraf) has designated Gen Z and Millennials as the primary target demographic. Tirtagangga Hot Spring Resort, currently undergoing rebranding efforts, aims to penetrate the Gen Z and Millennial market. Initial research suggests that Tirtagangga Hot Spring Resort faces challenges in attracting hotel guests from this new market. This study employs a quantitative approach, utilizing a questionnaire for customer analysis, and employs SMARTPLS for data processing and hypothesis testing. The research entails conducting interviews with 12 individuals, including business owners and their marketing department. The outcomes reveal a positive impact of Social Media Marketing on Brand Awareness and Brand Image, while Brand Awareness and Brand Image, in turn, positively influence Purchase Intention. Based on these findings, the authors propose several strategies to augment sales, leveraging the SWOT and TOWS tools encompassing both external and internal analyses. The recommended strategy revolves around diversifying promotional strategies that specifically target the hotel’s updated style and activities, aiming to captivate attention and generate interest. A key focus is placed on highlighting the hotel’s unique blend of modern aesthetics and hygienic surroundings. The promotional efforts should emphasize the newly adopted style of the hotel while concurrently advancing its renovation endeavors. This approach effectively showcases the hotel’s fresh aesthetic while preserving its renowned heritage. Additionally, the hotel should enhance its offerings by introducing supplementary activities and amenities, enriching the overall guest experience.
