All: Check your local weather records for record maximum and minimum temperatures and pack accordingly.
Typically, both wall tents and yurts can be made very warm if fitted with a metal woodstove---typically these are not airtight, so at night there is then a wild temperature swing down to near outside temperatures, unless someone gets up to feed the stove. Most packable woodstoves won't burn for much longer than 3 hours---some as short as 1 hour.
I would always pack at least a winter foam 'sitz pad' for breaks on the trail, and heavens forfend, an unplanned overnight. Ditto for bag or winter survival clothing.
A headlamp is good for unplanned nightime arrivals, reading, and finding the outhouse at night. A pee bottle can save a lot of bother too...
