For the biffy, take a piece of the pink foam and make a seat out of it. Keeps your butt nice and warm on those cold -whatever mornings. We've used coffee cans with the lids to store the tp in.
Also, keep a log book of some sorts. Date, what you did, who was there, etc. I've seen them range from nice leather bound jobs to literally writing on the wall. Makes for nice and sometimes interesting reading for everybody down the line.
