long night but you should be alright. Don't be afraid to let people know if you are getting too cold. I did one of these as a kid. I was up on a cot, cold, and couldn't sleep. But I thought it a good idea to go sledding in the middle of the night. Woke up some of the leaders who were concerned I had hypothermia as delirium is one of the symptoms. They gave me a pad, extra blanket, and some hand warmers. Didn't sleep much but wasn't out being an idiot either. Could of turned out not great. Good you will have lots of people around.
