A travel writer, writes about travel, that does not mean they travel.
Travel Writing Defind: Travel literature is travel writing of literary value. Travel literature typically records the experiences of an author touring a place for the pleasure of travel. An individual work is sometimes called a travelogue or itinerary. Travel literature may be cross-cultural or transnational in focus, or may involve travel to different regions within the same country. Accounts of spaceflight may also be considered travel literature.Literary travelogues generally exhibit a coherent narrative or aesthetic beyond the logging of dates and events as found in travel journals or a ship's log. Travel literature is closely associated with outdoor literature and the genres often overlap with no definite boundaries. Another sub-genre, invented in the 19th century, is the guide book.
