Prince Charles isn't with her. When he went on a cruise this summer, he left with his sons and an entourage on one plane and Camilla Parker Bowles on the other plane. He is still reticent about being seen with her in public.
Another one in great demand is Sophie Rhys-Jones, who is now Prince Edward's wife and the Countess of Wessex. She runs a PR firm.
Both Sophie and Prince Edward, a documentary filmmaker, have been accused of capitalizing on the royal connection. When Edward was on a recent trip to America, he got in trouble by opening his mouth in public. He criticized the British for hating anyone who succeeds and had to apologize later.
Camilla is likely to be more discreet during her visit, which is not a royal tour. She is on a private visit, although Charles has paid for an upgrade so she could fly on the Concorde.
