Duncan,
Sadly I never did get to Hadley Wood - it would have been during a company day for the company my younger son was then working for.
I knew Stoke Park as Stoke Poges in the days before the courses were modified. It was a lovely, if run-down, private club with sensible green fees. It is now very high end. Enjoy the clubhouse! Camberley, too, was in its days before its Japanese make-over and the introduction of that silly lake. Lovely course in those days, but a feeling of constriction with surrounding housing and roads.
Stoke Park's near neighbours are Beaconsfield and Denham, both Colt, and Mark Pearce could advise on other Chiltern courses. Otherwise, from Camberley, I'd head for Woking.
