This study is an interdisciplinary research since it is a combination of the expertise of International Hospitality Management and Tourism Management programs assessing the effects of hospitality development to the community of Sta. Rosa, Laguna in order to propose inputs for a tourism sustainable plan. Indeed, the study is a combination of quantitative and qualitative research. Survey questionnaires were utilized to know the effects of hospitality development to the host community. Then, to further intensify the result, key informant interview technique was used to know the strategies of the local government. The study revealed that in terms of the positive side, the environmental effect brought by hospitality development was significantly noticed by residents because of various programs launched by the city government in connection with ecological care. On the other hand, the residents felt the economic negative effect because of factors that they have experienced with relation to expenses. The study also showed that in terms of positive effects, the perception of the respondents has to do with their age, occupation, and length of residency. In terms of negative effects, however, demographic factors like occupation and length of residency affect their views. The local government of Santa Rosa developed different programs that helps maximize the positive effects of hospitality development as well as programs that can mitigate negative effects. This demonstrates that the local government has an understanding of the status of hospitality development and its connection with a sustainable plan. Likewise, the results of the study enlightened them on the deeper knowledge regarding inputs to be considered in the existing sustainable plan. In order to intensify the inputs, a certification by accrediting bodies is recommended to fully carry out the sustainable plan and measure the effectiveness of execution for continuous achievable results.
