At the eleventh hour Kensington Palace announced that the Prince of Wales would take his place and walk his daughter-in-law down the aisle.
On her visit to the newsroom, Camilla told staff: "It was such a lovely day. Just everything went right.
"We all wondered whatever would happen next and then everything went right. The only thing is that we are all losing our voices now."
Earlier she had said of the wedding: "It's nice to have something that is uplifting rather than depressing.
"Everything was just perfect, including the weather, which couldn't have been better. It was a beautiful day."
Camilla was at the headquarters of Independent Television News (ITN) to mark the 21st anniversary of its 5 News programme, which attracts 2.5 million viewers every week.
She got to tour the control room and gallery - "never a dull moment here, I can imagine", she laughed.
The Duchess even sat in on the morning's editorial conference, which was discussing an interview she had given on the issue of domestic violence to the programme's royal correspondent, Simon Vigar.
The issue is one of the cornerstones of the Duchess's public work and she has never shied away from raising what is a difficult subject for some in a very public way.
Asked about what made her seize upon such a "taboo" subject, she explained: 'It is a subject everyone knew about but rarely talks about.
"I talk to a lot of women and some of the charities involved and it just sparked something in me.
"I thought it was high time that we started talking about it. For some of the women involved it is very, very harrowing. It is a subject that has been under wraps for too long."
