George,
Lahinch is one of the few courses in the world that can be described as heaven. So, to me, without a doubt, the correct answer is Lahinch twice.
I would be remiss if I didn't acknowledge being one of the earliest critics of Doonbeg going back before the course was even built. The marketing hype that the British Army actually thought Doonbeg was a better place to build a golf course than Lahinch was just that: marketing hype. The property just wasn't that good and, IMO, the Norman team struggled to make sense of it as a golf course that would be enjoyable to play.
That said, I have some sympathy for Ian Andrews comments. If you want to visit Doonbeg to study golf architecture, that probably makes sense.
But, if you just want to enjoy real Irish golf, Lahinch wins by a wide margin.
