Going for #4 on PV Tuesday, I can only agree with you. Originally I thought it might lose it's shine after the first few rounds but I find myself giddy every time I go back.
The patio alone makes 18, lunch, another 18 so desirable. What a perfect place to hang out and watch people finish rounds between your 36 holes. I hope to go back some day!
If you don't need your clubs a day or two after you get home (I was planning to play so checked them), and are going through Heathrow I would really suggest shipping them. I am now waiting for my clubs to get to me as they were left in London... and have a 4 day tournament Thursday. Fun times.
1.) Pine Valley
2.) RCD
3.) Royal Dornoch
4.) Kingsbarns
5.) Eastward Ho!
6-7 would definitely include The Old, St Lucia, Pac Dunes. I loved North Berwick but it felt like a course I’d have to play 2-3 more times to really enjoy the quirkiness.
