A hammock can work both ways. I was on a trip last memorial day with a bunch of friends from college, our 31st annual canoe trip together, and the first night I was beat because of work and other things. I did not want to miss the fire time, so I hung not too far from the fire, got all snuggled down into my warm bag, it was 30 degrees, and simply lay there amongst them and listened and watched and recalled many memories from trips past.
I awoke the next morning to the sound of someone starting the fire. I drifted off at some point, yet it felt as though I had been part of the social life from the evening before. The advantage of a hammock is the flexibility. Unless you are in an area with no trees, you can hang just about anywhere. Even ground dwellers like some protection, so it seems to me there are lots of options.
This particular night, I was on a hillside by the fire and very much part of the group. At least for a while.
