We're entertaining on Monday so what do we do?

We bite off more than we can chew in the 'sort out and tidy up' direction!(added to all this they're forcasting 41ºc on Monday!) I had put up a shack to hold a load of stuff whilst I laid the floor in the last room of our house, then we were exiled for three and a half months by the virus and progress was halted. Never mind, it'll all get done before the dinner guests come on Monday!
