The hospitality industry is a broad category of fields within service industry that includes lodging, event planning, theme parks, transportation, cruise line, and additional fields within the tourism industry. The hospitality industry is a multibillion-dollar industry that depends on the availability of leisure time and disposable income. A hospitality unit such as a restaurant, hotel, or an amusement park consists of multiple groups such as facility maintenance and direct operations (servers, housekeepers, porters, kitchen workers, bartenders, management, marketing, and human resources etc.).
Usage rate, or its inverse "vacancy rate", is an important variable for the hospitality industry. Just as a factory owner would wish a productive asset to be in use as much as possible (as opposed to having to pay fixed costs while the factory is not producing), so do restaurants, hotels, and theme parks seek to maximize the number of customers they "process" in all sectors. This led to formation of services with the aim to increase usage rate provided by hotel consolidators. Information about required or offered products are brokered on business networks used by vendors as well as purchasers.
