Well first off you'd get in trouble from the advisory board for even planning an overnight. Second off, everyone has to get on the bus (multiple trips) there, and would then have to get on the bus going back. It's possible that you could hide and get a room yourself or something and avoid the bus, but then you're stuck without transportation or even a change of clothes. It's just easier to go back home. Plus we always had them at really nice hotels that you generally didn't want to pay for. And if you got caught, you'd go to standards.
