I've only done it once and it was more out of convenience than an real need. It was on a kill with my wife and son (10) on the side of a mountain at 40F , so that added to the fun and it was raining. Shelter with a 10x10 cuben tarp that we always carry and good rain gear. Wrapping son in a space blanket really kept him warm (and me when I stuck my hands underneath with him to get warmed up). We had a fire and just stuck it out. Having excellent headlamps to ward off the boogieman is nice. Plenty of water and calories to keep going.
