First to host are husband-and-wife team Paul Billington and Flora Loizou from Silverwood Lodge in Cambridgeshire, the only couple in this contest.
As the hosts show their three female guests to their rooms, Caroline, owner of The Dean B&B, has a frosty view of the fact that they don't live on site.
The hosts try to impress their guests by taking them punting down the Cam, but Sue from Seashells Guesthouse almost manages to capsize the group.
Over dinner, straight-talking Nancy from The Old Court Guesthouse suggests that not living on site compromises the hosts' attention to customer needs.
Come morning, Caroline has been kept awake all night by the noisy road and Nancy's TV 'doesn't work'. When the hosts read the frank feedback they are left livid and accusations of foul play fly.
