A hotel group is a collection of hotels that operate under a common brand or management. These groups can range from luxury resorts to budget accommodations, providing various services and amenities to cater to different types of travelers. Examples of well-known hotel groups include Marriott International, Hilton Worldwide, and Accor. Hotel groups often manage multiple properties in different locations, allowing them to offer loyalty programs and consistent quality across their brands. They may also engage in marketing and promotional activities to attract guests, ensuring a unified experience regardless of the specific hotel visited within the group.
