John,
I think Macdonald makes the distinction in his book:
“No course can be ideal which is laid out through trees. Trees foreshorten the perspective and the wind has not full play. To get the full exaltation playing the game of golf one should when passing from green to green as he gazes over the horizon have a limitable sense of eternity, suggesting imagination and contemplation.”
Yale is a classical course, because it’s inland. Laid out through trees!

Bret, I think you are right. I've read the book carefully and I was making it more complicated than necessary. Perhaps there might be more qualities of a golf course that CBM might place under one of the two categories of classical or ideal. I do think Macdonald sees a fundamental difference between ideal courses and classical courses. An essential element of the ideal golf course is location next to the sea on open, dune-covered land. I wonder if CBM would have considered the new Lido an ideal golf course?
Here's the paragraph which contains the quote you mentioned.
"I read much about ideal and classical courses; I used both these terms when I dreamed of the National, but I should like to make this distinction--no course can be ideal which is laid out through trees. Trees foreshorten the perspective and the wind has not full play. To get the full exaltation playing the game of golf one should when passing from green to green as he gazes over the horizon have an unlimitable sense of eternity, suggesting contemplation and imagination. This does not mean that a classical course cannot be laid out where trees are or where there is not the Atlantic, the Pacific or the North Sea to contemplate;
but there is a vast difference between the ideal and a classical course (my italics and bold). Yale is classical; St. Andrews, The National Golf Links and the Lido, the Mid-Ocean are ideal."
The ideal courses all are on the linksland next to the ocean or the sea and not laid out through the trees. They are both ideal and classical. Yale is in inland course so it's only classical.
