Because DH's work have suddenly decided that he and a colleague cannot be off work at the same time in the summer (and both men are married to teachers) we can't have a family holiday until the colleague is back - on A level results day.
Supposing DS gets the grade he needs, that would be no problem - chunnel and tent so no need to book. But if DS doesn't get the grades for his first choice, how long does it take to get through clearing? I can't be bothered with all the packing and driving etc just for a few nights.
