Hiya Carol,
I'm afraid I don't know all of the reality shows you've mentioned. But I would NOT do Big Brother... that's one thing I'm sure of.
I think I'd go for Changing Rooms, they could do up our TV room to look like a real movie theatre, that would be great. And it's not so confrontational as the others..
I did think of the Apprentice as I'm often found screaming at the telly, why don't they just... (I mean, selling tea to the French...) but I know I'm not assertive enough and I would just hate all the people I would be there with...
