For somebody who isn't interested in her role as you claim she sure keeps a busy agenda and schedule. You would be hard pushed to find many Royals, both in and outside the Arab World, who work as hard she she does.
I would have to strongly disagree with this statement. You can find many royals around the world who work harder than she does. Princess Anne and Prince Felipe of Spain are two individuals who come to mind. They are constantly doing public engagements in their own countries and around the world, and those engagements are not usually of the glamorous or media-magnet kind that Rania flocks to (especially abroad). They do the mundane engagements that enable them to be seen by a broad range of society. I've noticed that especially with Prince Felipe. You constantly see him in the public eye, doing his job. Princess Anne, meanwhile, has a notorious work ethic I think more royals should emulate.
When compared to Felipe and Anne, Rania doesn't have nearly as busy a schedule as she should for a queen. She travels a lot, and I think that might make people believe she has a busier schedule than she does. But even then she puts in no more than one engagement a day, if that. I've watched solo trips to the United States where she has done an average of one engagement every two days. And I've never seen her make solo foreign trips to the less glamorous spots of the world – it's always to the U.S., other parts of the Arab world and a few countries in Europe. When she's in Jordan, she'll do a spurt of engagements and then disappear from public view for a while. This year she enjoyed three vacations in the first three months, and likely has more planned. And she always seriously scales back her activities in the summer, supposedly to spend time with the kids. So once this month's flurry of travel is over, we likely won't see much of her until the fall.
I think she still cares a great deal about her clothes and I suspect those long absences from the public view involve shopping trips to London and Paris. She is constantly debuting new clothes even though she is, admittedly, repeating a few more clothes than she used to when she first became queen. But it is still way too much for a queen of a poor country.
Just my opinion.
