If you were going to travel to Spain to play golf where would you get help to choose where to go?

Would you use a website and if so which one or ones?
Would you go to your local travel agent?
Would you go on a friend's recommendation?
Would you ask on a forum like this?

I'm asking cos I was asked the question by somebody who has an apartment in Spain and wants to attract golfers.

I simply searched using Google but are there any sites that people would recommend or have used etc.?
