I would never discourage anybody from doing anything. I look for positive things in everything I do in life and there is usually something positive to be found from playing golf wherever that may be. I have played in Greece and I have played in Cyprus.
While Glyfada in Athens, one of only two courses on the Greek mainland, was excessively urban and rather a dull course in poor condition it was still fun and the two or three good holes stuck out in the memory the more for it. It was right next to the old main airport and must once have been horrendously noisy. When I was there that old airport was being used for training for the security police who might have to deal with terrorism at the Athens Olympics. My round was punctuated with grenade explosions, machine gun fire, helicopters making low-level attacks and people driving police cars along the runways at horrendous speeds. There was nothing dull about such a round of golf.
Tsada in Cyprus was a real plus. It's located in olive-clad hill country well inland from the topless beaches and instant-food emporia of Paphos. Old women (at least, I assume they were old) with donkeys looked after flocks of scrawny sheep or smelly goats while I played pretty well alone on the course, up and down hill with great, unspoiled views, the scent of wild thyme, wild rosemary and goats in the air, a monastery to circumnavigate and all hell if you missed the fairway - tees, fairways and grens were watered, the rest of the course was bone dry, rocky and - well, you'd never find the ball, so why bother looking? I don't know Crete, never having been, but its golf course has got to be quite unlike anything else you have ever played - do it, take lots of pictures and share them with us here, even if it's rubbish. It's better than lounging on a beach all day trying not to look at the topless bathing beauties (or, rather, trying not to be seen looking) or being eaten by a minotaur.
