Steve,
Clearly the best thing to do is use the car regularly, but if you can't then I'm not sure that just letting the car sit at idle for an extended period is the best alternative. As the handbook says, it's best to start the car and then drive away ASAP to get the engine up to temperature quickly to minimise wear on the moving parts.
Of course, it's not just the engine but all the other parts which need to be exercised too - transmission, wheel bearings, etc. and in order to get the engine oil up to temperature really you need to give the car a decent run of 10 miles or more.
I'm not sure if that helps your situation but I think that somehow you just need to find a way to get out and drive your Cayman on a regular basis.
