The origin and growth of the hotel industry can be studied under the following three periods:
1. Early Period: This refers to the time before modern hospitality concepts, where lodging and inns existed to serve the basic needs of travelers, primarily for resting and food.
2. Medieval Period: During this period, inns and guesthouses became more organized, and the hospitality industry started to evolve with a focus on providing comfort and service to travelers.
3. Modern Period: This period saw the establishment of the hotel industry as we know it today, with the development of large hotels, international chains, and a professional approach to service, marketing, and management.
