In this paper, we address the issue of globalising language in the hospitality/tourism industry, as one of the key ingredients of sustainable development. English is and has been considered as the lingua franca of business, which is acceptable worldwide, and thus, it needs to be promoted as the medium of communication especially in the tourism/hospitality industry. Travellers/tourists often prefer to visit a country where communication is not a problem. Unfortunately, the language barrier is still one of the priority concerns of the hospitality/tourism industry, particularly in some Asian non-English speaking countries. A home/hotel/restaurant/tourist spot/school/office/village/ nation that is friendly communication-wise has always that charm of enticing visitors/guests to come back. Guests that keep on coming back imply repeat business, which ultimately would add figures into the bottom line. Globalising language may help to eliminate the issue of language barriers, and thus help to promote the hospitality/tourism industry.

In this paper, we calculate the related costs of transport, food, accommodation and time involved as well as the rate of visits as compared to the costs, and the benefits from the Alayan Cave System (ACS), by using the Individual Travel Cost Method (ITCM) to determine the educational and recreational values of the site. Data came from the linear recreational demand for the site at the Department of Tourism -RO2 statistical records. We also determine the expenditures of the guests on off-site and on-site tourism-related activities and establishments to provide a more solid base for tourism policymakers, planners and decision makers in the region, towards a better tourism tax system for the sustainability of the ACS. Study outcomes provide insight into how the locals or indigenous people living nearby can take advantage of the benefits/opportunities derived from the site.
