My wife and I do a lot of solo trips (especially last year). All things equal we will take the smaller available camp. But some camps may be necessary for a particular hike, winter sun or summer shade, etc., In that case we'll set up in a corner and, sometimes with a little screening, welcome other groups to share. We've made several friends and had some memorable conversations and jam sessions. I have little patience for groups that feel entitled to a camp over smaller groups who have paid just as much their permit.
