I'm not really sure. I know the night before they provide a place to stay (My daughter is sleeping in the art quad, or at least outside in sleeping bags,
) I'm not sure what to do about the other night.
I would probably just give them a call and ask. I had to call them about another matter and they were very friendly and helpful. Their number should be in some of the email you have recieved.
Which one are you going on? My daughter is doing the 6 day hike through the Adirondack's.
