Most big game seasons I'll tent for 3-4 nights a time or two with my wife or a friend in a 10X10 Cabelas "spike" tent with one central pole. It sets fast, has a floor, and handles rain, snow and wind, which invariably arrives sometime during the outings. A big winter bison hide on the floor makes it luxurious! I never heat it, but there is enough room for folding chairs to cook in it for quick meals or a pot of coffee water. "Hot Hand" chemical packs make boots and gloves fantastically warmer. However, the last time I elk hunted from it at elevation, I did get a touch of frostbite after sleeping one night in fingerless gloves... fingers peeled for days. It is nice to get out of the roads for a couple days, really dials me into the game much better than can be gotten from a loud vehicle, and; usually gets me afield an hour or two earlier than anybody arriving afield via wheels.
