As Roger implies, with the short days of winter you usually have little time to play in camp. Keep your XC boots on for setting up camp and meal preparation. Also keep your gaiters on. They proivide about another 10 F. of warmth.
Take them off when going to bed. With single boots just put 'em in an open stuff sack (so they can dry if you neglected to wear a VBL sock during the day) and then place them in the foot of your sleeping bag overnight.
For double boots remove them from the outer boot and put 'em in the foot of your sleeping bag. THIS IS A MUST to avoid the agony of frost nipped (or even frostbitten) toes in the morning. Place the outer boot
shells "telescoped" together at the cuffs & then in the tent vestibule. This keeps most spindrift snow out of them.
Camp booties, down or synthetic, are great for hut skiing – almost a necessity.
P.S. Don't forget lip balm and 50+ SPF sunscreen!
