I'm personally getting a little hung up on the difference between a worthwhile interlude and an incredible reveal. I can think of numerous breathtaking reveals, such as the 4th at Bethpage Black, which several have mentioned, but there really is no interlude there. However, I think "great interludes" on a golf course are pretty rare. One place that does have some fine interludes is the Dunes in Michigan. There are a couple of walks through the forest, particularly when playing certain tees, which are very pleasant breaks with significant anticipation of what is to come next.
