I'd love to come over and meet up, if it all fits in. I agree that London is not the ideal place to visit during summer months, unless you have loads of energy, or really want to shop. I have saved some links that you might want to have a look at. The Oxford and Cotswolds areas are nice, and easy to get to from London.
