One Direction don't want to get lonely on tour, so they will have friends and family with them as much as possible.
Harry Styles - whose group kicked off their 'Where We Are' concerts in Colombia last week - will be on the road until October and wants to avoid homesickness, so he and his bandmates are planning to have as many visitors as possible across the globe.
A source said: "The boys got so homesick last time and wanted to make sure they had friends and family with them during this tour.
"They find hotel rooms so lonely.
"Harry has divided up dates between his parents, sister and friends so that he isn't by himself for much of the tour. Harry's dad Des and mum Anne will fly out separately during the American leg."
Harry's father Des has already revealed when he will be going on the road with the 'Little Things' stars.
He tweeted: "We're doing Manchester, London, Dublin, Milan, Madrid and the US leg from Nashville to Dallas."
Meanwhile, Niall Horan has a group of friends who want to join him on tour, Zayn Malik will try to fit in visits with fiancée Perrie Edwards as often as possible, and Louis Tomlinson and Liam Payne will spend much of their time with girlfriends Eleanor Calder and Sophia Smith.
The source added to the Daily Star newspaper: "Niall has a close-knit group of mates from Ireland and he wants to them to be there.
"Louis and Liam also hope to have their girlfriends travelling with them for most of the time. And Zayn will see his fiancée as much as possible.
"They all just want a bit of home with them."
