In recent years, the rural homestay has developed rapidly against the background of rural-revitalization policies. However, in early 2020, COVID-19 broke out in China, and the homestay industry was faced with a great challenge. It was difficult for self-employed homestays to resist the risks of the pandemic. As a result, defective operation and business failure occurred in some regions. However, rural homestays with a background in the brand, chain and cluster development mode persisted in the market with a diversity of operation principles. This paper tries to set up an evaluation system for understanding the occupancy needs of tourists, in order to improve the ability of rural homestays to resist risks. The article offers a methodology for assessing the tourist experience of rural homestays in coastal areas, with homestays in Dapeng New District of Shenzhen taken as the research objectives. Then, the evaluation system of rural homestays is set up from the perspective of tourist experience. Based on the results of a questionnaire survey and interviews of operators, this paper proposes the tourist experience–importance analysis in Jiaochangwei and Xichong by the importance–performance analysis (IPA) method. Finally, it suggests policy recommendations that can resist high risk based on tourist experience, for the sustainable development of rural homestays in China.
