I have the luxury of going camping more than once a year and close enough so the travelling to get there isn't an issue.  I do take at least one trip yearly with 3 to 6 others.  Not close friends, but some have become closer friends over the years.  Last year went with an entirely new couple.  Generally no serious problems.  I try to find others with some camping experience already, so they understand what they are getting into.  I also try to determine if they are fit enough for the exertion.  We all take our own tents, be it in singles or couples.  So snoring isn't much of an issue. This gives you a quiet place to get away on occasion when you need it.  We also take 2 to 4 canoes/kayaks; again so we can do some things separately when the opportunity presents itself.  We try to divy up the camp work chores, if someone isn't volunteering, I am not shy about asking them to do something.  They are usually glad to have something to do and feel usefull.  It is easy to get caught up in the idea that since they are inexperienced they can't do it "right".  Who cares, they need the practice!  Sometimes they complain, but I have found those are the challenges they end up remembering and in some demented way fondly looking back on.  IC
