Happily, the informed Golf Club Atlas reader can avoid being so shystered!
Malcom,
With a recent Father & Son trip completed in June, I disagree.
1) We played Ballybunion as the guest of a Member and also as the traditional American tourist. They were great to us both ways.
2) Lahinch was probably the most expensive and I just loved it. We played in a fierce wind and the place was buzzing in anticipation of The Irish Open.
3) I am an Overseas Lifetime Member at Enniscrone, and have not been there in 8+ years. Honestly when I was booking our rounds I assumed they would have "lost my membership". They treated me, my son, and my guest like royalty. We were invited to the Monthly Dinner where they give out awards for the past month's competitions, and it was an absolute blast to be there.
4) My only regret is I read too many GCA post about Portmarnock being overrated. We only had time for lunch and a quick tour, and I regret not setting up a game. Love what I saw. We played The Island Club and the Pro there was simply great to us.
Having flown into Germany last summer (family trip, no golf), my other ethnic heritage, versus Ireland this summer, it is not even close. The Irish are very welcoming.
