I did a good bit of clunking on Fins and Things so I knew after day one that I wanted to stay on the "bunny" trails. No worries about overachieving here.
I think all that's needed are deadlines for decisions to be made and runs to start (as Gizmo42 suggested). Sue was my proxy at the Stoop but even she didn't know what was going on until really late at night or fairly late the next morning. Tuesday went great, but on Wednesday I got a phone call saying we were leaving in an hour I think, and then it was 3 hours after that before we actually left. And then Thursday morning I got a phone call saying we were leaving in 15 minutes (which did actually happen). If I did want to go (I had already decided to give the girls the day off because they were exhausted) packing up the kids, loading the cooler in the car, and driving over takes at least that long, so I probably would have missed the run anyway. Again I realize that's fairly unique to my situation and it wouldn't be a problem for most.
Maybe decide on at least the novice trail and leader/tail each evening by 9 (gives time for everyone to grab dinner and then discuss on the Stoop) and then plan to leave each day at 9? I agree there's no need to publish the trail schedule online if you have a proxy at the Stoop. As long as a decision is made far enough in advance to let off-siters know I think you're good to go.
