The floor of the shelter took a while to warm up and even once I had was not a very comfortable sleep. I tossed and turned all night with every angle hurting my back or my hips. That said, it did rain off and on throughout the night, and all of my stuff, including my tent stayed as dry as it was to begin with.
Which is to say that when I finally got up at 6am, only my shoes and socks were damp, as they had been when I took them off.
