Thanks. So far the damage seems to be 2-3 metres by 5-10 cm and one area in the corner that may be 20x20cm. I have the central fan going and a small stand alone fan. Do you think it could wait until tomorrow to hire the steam cleaner or should I do it now?

My main concern is about the underlay being wet and turning mouldy. And if I rip up the corner of the carpet, how do I stick it down again? Luckily a bed is along both those walls, but still.
