“One must travel, to learn,” said Mark Twain (1835-1910). These words from the American writer are still close to the hearts of many holidaymakers today. Apart from relaxing, they are interested in exploring the country and its people, culture and culinary customs at the destinations. To do so, they can choose from the 150,000 excursions and other activities offered by TUI. Our series “Discover the world – with excursions at TUI” casts a look behind the scenes of the excursion programme – from the technological developments all the way to the organisational efforts delivered by TUI employees.
