There was no forcing involved. Since there seems to be a lot of interest in this, I'll go into more details. As I said, this was discussed with organizers at the time, largely it was largely a matter of "the kids'll figure it out" failure. Some specifics will be vague due to time.

This event was a camp out. They had tents for the campers, but it was, in my kids view, a free-for-all. Like a "go figure out the tent situation", and my child couldn't figure out the tent situation, so decided to sleep outside. And woke up with a bunch of bugs (I don't remember exactly what, leaches sticks in my mind). So they decided they'd caffeinate the rest of the event and not sleep.
