I dont think CdA green fee prices have been published yet. We are all waiting for that with anticipation.
When you play at any other Polaris course you can pay a resident fee which is usually around 20 euros less than non residents pay. Your father in law should also be able benefit from this. Whenver I play at the other courses I just tell them i am CdA resident and they automatically give me the lower rate.
To see green fee prices check the Nicklaus Golf trail link on the main Polaris World site.
Hope this helps.
