Public reaction in Britain to Camilla's decision not to attend today's service has been largely positive, if caustic at times. "I couldn't be happier if I'd won the lottery," Joan Berry, secretary of the Diana Appreciation Society told newspaper The Telegraph.
Robert Lacey, historian of the British Royal Family, said on reflection Camilla probably shouldn't have been invited at all.
"It wasn't appropriate," Lacey told ABC News. "I think when it started it seemed a nice tribute by Camilla to Diana. But as people thought about it more and the press got more upset about it, that changed."
Today's service is being held at the Guards Chapel near Buckingham Palace in London. About five hundred people are expected to attend.
After spending today at Raymill House, her country estate in Wiltshire, Camilla plans to take a holiday with a small group of girlfriends, supposedly on the Greek Islands, according to the Daily Mail.
Clarence House does not comment on the private travel plans of members of the royal family and would not confirm or deny the Duchess' vacation plans.
An unnamed source, however, told the Daily Mail: "This is a long-planned trip and there is nothing untoward. The couple normally enjoy separate holidays at some point."
