The hospitality industry is unique among industries in terms of its depth and extent in daily life. From lodgings such as hotels and serviced apartments to catering and entertainment, as well as travel agents and cruise lines, hospitality plays a significant role in both leisure and industry. Most industries are dominated by a limited number of companies — a handful of global brands. However, due to the diversity in hospitality, the number of well-known companies involved is also remarkable, including global hotel and restaurant chains, travel operators, and many more.
