A very exciting idea. All the guests would enjoy watching them.
However Ian and Camilla's website needs a bit of editing. I had a glance and picked up the following:
"About Ian & Camilla
They started out their careers as competitors...... "
Why the "out"?
also :
"..reached the final with Athlete Denise Lewis..."
Why the capital A for athlete?
I didn't read any more and obviously that wouldn't put me off Camilla and Ian, I think they are marvellous, but if I didn't know them and was just browsing, I would consider mistakes like those sloppy and I'd move on to another couple. A website is a showcase.
Sorry, I am nitpicking (insomnia!).
