I would posit that a course can't be truly great unless the whole is greater than the sum of it's parts. Obviously a great course must, by definition, have a number of great holes and few, if any, really weak ones. However, it's the routing, sequencing, variety, ebb and flow, crescendos and quiet passages, and how they come together, that makes it an experience and not merely a good day on a collection of driving ranges and short game areas. Take Ravisloe as an example- a bunch of really good holes, but the course, in it's current presentation, is significantly marred by the fact that 7 of the last 11 holes are par 4's of very similar length. Where's the climax? too early in the round...Pebble is an interesting case, and I hadn't really thought of it in this context before. Until now I've felt that the course is somewhat overrated as there are too many pedestrian holes amongst the all-world ones and scenery everyone loves. But perhaps it is precisely the fact that the great holes come in bunches and allow for two movements, if you will, so that the weaknesses aren't as bad as they might be on another course given the sequencing and flow of the round. It's the journey man....
