More than 30 hotels across all 10 Tui destinations in Mexico and the Dominican Republic will offer free child places, which Tui claimed was “an industry-leading deal”.
It added “thousands” of free child places were also available in Florida, Turkey, Cyprus, Greece and Egypt, including during the school holidays.
Chris Logan, Tui UK and Ireland commercial director, said: "We're thrilled to be the first major tour operator to extend our free kids' places programme to Mexico and the Dominican Republic, responding directly to the growing demand we've seen for long-haul family adventures.”
