Brilliant . I've found this map and from what you've all said it has become clearer, I know this is post changes but I have the layout of the terminals which helps and will the girls. I was really worried that they may miss their flight to Lima as they have another flight to get from there and then they are booked on a research expedition the next morning which will leave without them if they're not there. I did try to get them a flight where they could overnight at CDG but it didn't happen...long story!
