The boys and girls face their biggest test: living with the opposite sex. It's not a prospect that thrills everyone - and as the girls make a grab for space they test their limits of the boys' hospitality...
For Lorna, who felt like an outsider in the girls' village at times, the move is the best thing to have happened. And a budding romance between Maddie and William has village tongues wagging, so Maddie decides on a solution to throw everyone off the scent.
There's one final treat for the children: a dance with a rock 'n' roll band. They'll need to get dressed up to the nines and learn to dance together. But the idea appeals to some more than others...
And as the fortnight-long adventure draws to an end, it's time for the children, and their parents, to reflect upon what they've learnt about themselves.
