Weeds everywhere -- help!

We are on holiday for 2 weeks very shortly, the father in law is in charge of the allotment while we are away. Not sure he will be able to cope with what we need to be done, as its very local to us we go down every evening or every other evening to water and weed with the dog.

My friend is lending my her hoe, must get planning on what we will do in preparation for us being away to keep the weeds down.
