You may be aware of this, but Lahinch has a 45 euro replay rate, which you MUST take advantage of. It's defintely worth playing the Klondyke and Dell holes twice, as well as the rest of the holes, of course. A pair of members joined me for the second round (one of them was on the greens committee), which was a great experience, especially considering the complicated history of the course. I also played, Killorglin, Dooks, Donegal, Narin & Portnoo, Enniscrone, Carne, Achill, and Connemara, finishing at Lahinch. All the links courses were great, with probably the most pleasant surprise being Enniscrone. If I had to skip one, I think it would be Connemara, but again they were all great experiences.
