Lodging chains are groups of hotels or accommodations that operate under a common brand name and standardized services. These chains provide travelers with consistent experiences, making it easier to find familiar amenities and pricing. Examples of popular lodging chains include Marriott, Hilton, and Holiday Inn. These chains often have locations in various cities and countries, catering to different types of guests, from business travelers to families. By leveraging their brand recognition, lodging chains can attract more customers and offer loyalty programs that reward frequent visitors with discounts and perks.
