Hospitality businesses are open 365 days a year and 24 hours a day. The hospitality industry is a broad category of fields within the service industry that includes hotels, restaurants, 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.
