A travel guidebook is a book for tourists or travelers that provides details about a geographic location, tourist destination, or itinerary. It is the written equivalent of a tour guide. It will usually include details, such as phone numbers, addresses, prices, and reviews of hotels and other lodgings, restaurants, and activities. Maps of varying detail are often included. Sometimes historical and cultural information is also provided. Different guide books may focus on different aspects of travel, from adventure travel to relaxation, or be aimed at travelers with larger or smaller travel budgets, or focus on the particular interests and concerns of certain groups, such as lesbian and gay singles or couples. Guidebooks are generally intended to be used in conjunction with actual travel, although simply enjoying a guidebook with no intention of visiting may be referred to as “armchair tourism”.
