According to a royal expert, the couple is aware of the importance which lies on the trip to alter the public's view toward them.

"They and their aides know this tour has to be a success, and everything has been planned meticulously so there is no margin for error," they told Vanity Fair.
Royal author Ingrid Seward was another expert to voice the same opinion.
She thinks that Archie will be used to aid the couple in their desperate attempt at regaining public support, according to The Sun.
Until now, the 5-month-old has only been seen in public twice, the last time at the King Power Royal Charity Polo Day where he supported his father.
It has not been confirmed that he will be present at their engagements in Africa.

Seward told The Sun: "People will want to see baby Archie who could be the key player in this. I think if they show a glimpse of Archie it could turn things around for the Sussexes.
"It's a small thing but it could end up being a very big thing in terms of better press coverage. They've had a tough run, this is a chance to make it better."
The Duke and Duchess of Sussex are currently among A-list guests in Rome for the wedding of fashion designer Misha Nonoo, without Archie.
