"They have decided that their children, Prince George and Princess Charlotte, will travel with them and we expect the children to be seen on at least a couple of occasions over the course of the week'".
Prince William and the Duchess of Cambridge are, after all, determined their children grow up in private and not in the public glare.
Perhaps the penultimate event of the royal tour will be when William and Kate take their competitive streak to the water as they captain crew boats in Heidelberg.
But William and Kate will also experience modern-day Poland, meeting with young entrepreneurs at the top of a Warsaw skyscraper and also tour the new Gdansk Shakespeare Theatre.

Plane makes emergency landing after passenger 'passes gas'
A passenger caused a stink aboard an American Airlines jet, forcing an unplanned landing at Raleigh-Durham International Airport. American Airlines, however, said the smell was due to a mechanical issue.
Prince George, who turns four this month, walked down the steps of the plane while his two-year-old sister, Charlotte, was carried down by her mother, Kate.
The beginning of any royal tour is always marked by the striking photos of the family disembarking from a plane, and, this time, we were greeted with all four royals making their way off the jet.
"The Duke and Duchess [of Cambridge] are very much looking forward to this tour and are delighted with the exciting and varied programme that has been put together for it", the Royal family's official website said.
Prince William and his wife Catherine are welcomed by the Polish President Andrzej Duda and his wife Agata Kornhauser-Duda at the Presidential Palace in Warsaw 17 July 2017.
Later today, the Royal family is set to visit the Warsaw Rising Museum, as well as the Heart in the Warsaw Spire building where they will see the city's panoramic views. Later this evening the duke and duchess are scheduled to attend a formal dinner at the Royal Łazienki park.
