Abstract: In recent years, with the continuous development of tourism in the Guangdong-Hong Kong-Macao Greater Bay Area, the free travel model has gradually become an important form of tourism in the region, especially favored by domestic and foreign tourists. From the perspective of tourist experience, combined with the unique tourism environment of the Greater Bay Area, this study discusses the current situation, advantages and challenges of free travel in the Greater Bay Area. By analyzing the needs and feedback of tourists, we proposes strategies for optimizing the existing tourism services and management systems, including improving cross-border transportation convenience and tourism information services, strengthening cultural tourism experience and cooperation between cities. This study aims to promote the high-quality development of free travel in the Greater Bay Area and provide theoretical support and practical countermeasures for the sustainable growth of regional tourism.
