We have a fireplace and got some gas logs installed. I am enjoying them this morning, in fact. Also, if you're careful, a space heater parked near can certainly warm up a place.

As far as movies, "Blue Hawaii" is a good one, particularly if you like Elvis.

And definitely something hot to drink, as you suggested!

I do keep some lights on in the den even during the day and make certain to open the blinds.

Keep warm!
