Harry: "Playboy Prince" No Longer?

Prince Harry wraps up his whirlwind, 36-hour first official visit to the United States Saturday with a visit to a community group in New York City's Harlem, and a charity polo match.

A stop at the World Trade Center site was among the highlights after he arrived Friday.

Observers say image-polishing is high on Harry's list of priorities during the visit.

Buckingham Palace "is determined that the royal wild side won't surface on this trip," says CBS News correspondent Elizabeth Palmer.

One of Harry's polo teammates on Saturday, Emma Tomlinson, told CBS News, "It's very important to Prince Harry that money is raised for this wonderful charity, Sentebale."

Sentebale, founded by Harry in the tiny African kingdom of Lesotho, helps finance homes and education for AIDS orphans, a cause first embraced Harry's mother, the late Princess Diana.

Royals watcher and entertainment journalist Katie Nicholl of the British newspaper the Mail on Sunday said that, as of when she spoke on The Early Show Saturday Edition, the trip had been "a huge success" for Harry.

She told co-anchor Chris Wragge, "I was looking at all of the official engagements (Friday), and he really suited the part. I mean, he has very much the same actions as his mother. At one point, he crouched down to greet a little girl whose family had been lost in 9/11. And you just thought, 'Harry really has this personal touch.' And I think it's something that's going to endear the world over to him and the royal family. I think it's very important."

Harry was "completely engaging" on Friday, Nicholl continued. "I spoke to him afterwards and he said how amazing it was for him to meet these people. I really think it's important that he's come over here. ... I think it's gone very well for him."

Nicholl said she doubts reminders of Harry's well-known checkered past will surface during Harry's brief New York stay: "I just don't think it would happen on this trip. The queen has paid for it. ... This is a very, very serious trip. This is not a playboy prince. And I think Harry, more than anyone else, wants to prove that point.

"I think Harry has matured massively over the last few years. Yes, there have been mistakes, there have been errors along the way. But the most important thing is that he's learned from them. And, what he said last night is this that this all about Sentebale for him. ... That, actually, is hugely important for him."
