6 to 7 at Dormie isn't bad, especially since it's downhill. People only notice it because of the existence of the 14 tee right in the way. I'd vote 17 fairway to 17 green as the hardest walk on the course (especially coming at the end of the round), and 8 tee to 8 fairway replaces 15 tee to 15 fairway as the most "out of the way" with the walking bridges installed now. All things considered, it's a really nice walk given the land it's on. Arguably they could have taken 30 seconds off your round by roughly going 6-14-15-16-8-9-10-11-12-13-7-17-18 and reconfiguring 7 & 16 a little such that going around 16 to 17 wouldn't be bad, but I don't think the course experience would be better for it. Just enjoy the sneak peek of 14 to your left and the view of the lake to your right.
Everyone points out the one at Bandon, and I would have, too, until going out there again last month. After 152 holes for the week and 31 on the day, play was slow and I decided to forgo the shuttle. It's really not that bad of a walk, and it's a really nice walk through the woods with a great view payoff at the end. Maybe it's not Cypress Point, but I really enjoyed it and feel like it giveth rather than taketh from my experience. It was certainly better than listening to the truck engine as it lugged us up the hill. It is called Bandon "Trails" after all.
I'm not sure I'd call it a "tool", but I would imagine C&C clearly think about these longer walks as part of the experience of playing the round. It sounds like they had the option of building a bridge and using some land east of the "volcano" hole at Sheep Ranch and elected not to. Cramming all 18 west of there clearly had some trade-offs, particularly the congestion of tees and greens near the south end of the property. Maybe it was simply that the holes over there wouldn't have been worth it, but the bridge walk was probably part of the calculus as well.
