Frank,
As Scott has already suggested, you need to head for Royal Worlington and Newmarket. Its about 30 mins drive from Cambridge. The University golf team play there, Colt mad amendments to the course and Darwin loved it. When I played last year I virtually had the course to myself, greeted by name by the steward, breakfast beside a log fire, a swift nine in the rain, another in much better weather, then lunch with a couple of plus four clad old boys over claret while their dogs waited patiently outside. If you are only playing one course in the area, this is the one:

An hours drive north will bring you to Luffenham Heath:
http://golfclubatlas.com/forum/index.php/topic,42028.0.htmlIf you fancy links golf, both Hunstanton and Royal West Norfolk (Brancaster) are just over an hour and a half away. If you make the journey 2 hours long then that brings the following into consideration: Woodhall Spa, Notts (Hollinwell), Beau Desert. If you fancy either of the last two, I'd happily join you at Beau (as would Sean Arble I expect) or I'd happily host you at Notts, if we could get diaries to work. But much as I'm happy to promote golf in the Midlands, I still think RW&N is your best bet!
But by the time you are driving 2 hours, you also bring the likes of Huntercombe into the eqasion as well as a lot of the london heathland courses, but with the caveat that any journey around the M25 can tale much longer than expected, so is probably best avoided.
Cheers,
James
