I played a couple of rounds there a fortnight ago.
The comments made thus far are accurate. The rough is really penal and they are severely restricted with what they can mow. It is a very rustic experience, with a lot of blind shots and some very demanding carries. First time out, you will frequently be hitting into the unknown and it pays to be as close to the centre line of play as you can to account for some very random kicks off of unseen dunes. If you get out of position you are well advised to take your medicine and just get back into play, where you can see it.
I really enjoyed it, because it is exactly what I was hoping it would be, a throw back course. Although I've never been there, there are clear similarities with the kind of wilderness experience you would get at a place like Askernish, or Sand Hills. It is very peaceful and totally unpretentious in its presentation. It is also very empty just now.
One could be critical of the 'blind' fairway contouring, but without knowing what restrictions were placed on them, it is unclear what other options they had to circumnavigate the protected habitat areas.
The greens are a real feature, clearly more undulating than the Castle Course IMHO. However, as many of them reside in gathering hollows, they are quite receptive and I found them to be a lot of fun to play to and putt upon. They' re pure fescue, so they are not especially quick.
They have just shephereded a flock of sheep onto the course, who will be the only means of cutting the deep rough. They had already left their mark on the 12th green when I was there and were taking a fancy to the blow out bunkers. Once they have munched their way through the roughs it will be a much more enjoyable test for the average golfer. For now, it is very demanding, perhaps one of the three hardest courses I have played. Apparently, several vistors have said that they really enjoyed the course, but will leave it a few years to come back, once the conditions have eased up somewhat. Enjoy it for what it is now, a very rugged, wild test.
I should also point out that the staff at Machrihanish Dunes were exceptional. You could not wish for a warmer, more friendly welcome.
I also stayed in the B&B you're staying in Chris. It was great. You'll be very comfortable.
Happy to give more feedback if anyone asks.
