The feeling of solitude can be a nice one to have on a golf course at times; Pilgrim's Run (Mike DeVries) near Grand Rapids, Mich. stands out in my experience as a course where that feeling of isolation adds to the sense of a journey.
But overall I like to have the sense that other people are nearby, enjoying themselves as much as I am. I reckon that if anything, promoting a feeling of togetherness and shared experience on a golf course becomes more attractive as the rest of life starts to feel more isolated and siloed.
When executed well, routing junctions where several holes meet are really nice additions to the flow of the round and the social experience. One course that does this really well is Crestview CC, a Geoffrey Cornish course in Agawam, Mass. There's a little roundabout and hut you'll pass on the way from 1 green to 2 tee, from 6 green to 7 tee and from 16 green to 17 tee.
Another Cornish course, Hop Meadow CC, where I first learned to play, has this quality as well. You walk by the snack bar on the way from 8 green to 9 tee, from 10 green to 11 tee and from 15 green to 16 tee. That's a lot of chances for a very good hot dog and/or an ice-cold Snickers (not always in that order).
