When we were digging out we didn't poke holes out the top so we left the door open a bit so it became a bit chilly in the early morning so I was a little uncomfortable in the night ( there was also a lump under my hip that I couldn't get rid of so that sucked) but everyone else in my group was fine they said . We had candles to light the quintzee which also made it smell so good and heated it a little, but we blew them out before bed so I think that also made it colder as well.
I think that if we had a fire that would have been a lot better because I was a bit chilly when we were just chilling but my friends were complaining that hey were cold most of the night so I think that would have helped. Because it was our first time we didn't plan everything that great so there were probably some things we could have done to stay a little more dry to keep from getting cold so that will definitely be noted for next time.
Other than those few thing I think we had a really good quintzee that kept us all pretty warm and comfortable. would I do it again? Probably not because living in a snow bank isn't really my stile but like if a friend asked me to I might do it again.
