An important transitional figure from the idiosyncratic style of the Grand Tour travelogues to the more informative and impersonal guidebook was Mariana Starke. Her 1824 guide to travel in France and Italy served as an essential companion for British travelers to the Continent in the early 19th century. She recognized that with the growing numbers of Britons traveling abroad after 1815 the majority of her readers would now be in family groups and on a budget. She therefore included for the first time a wealth of advice on luggage, obtaining passports, the precise cost of food and accommodation in each city and even advice on the care of invalid family members. She also devised a system of !!! exclamation mark ratings, a forerunner of today's star ratings. Her books, published by John Murray, served as a template for later guides.
