Last all-nighter I remember was on a school "study" trip to Portugal and Spain(there was a total of 40 people on the trip[5 instructors and 35 students]) last May. It was of course about the Food and Wine of the regions. Anyways, the last night we had a party in one of the bigger hotel rooms(we crammed 25 people in there, and played sociables), we eventually got kicked out by the rooms inhabitants(they wanted to sleep), so about 15 of us went to another room to keep playing/drinking/having fun. By about midnight(we had started partying at like 5pm) 90% of the people were asleep, and only a few of us were up, talking on the balcony. It widdled down to only 3 of us, and we decided to go out for a walk around town. Filled 2 gatorade bottles with booze, then went around taking random fun pictures. We all stayed awake until we were sitting, waiting for our plane. I was the last one to fall asleep, and it was on the plane. I dont even remember buckling up, I just remember sitting, then waking up to walk off the plane.
