We keep the thermostat at 55 and heat the living room with a space heater when needed. The living room and kitchen are the rooms where everyone hangs out, I see no reason to heat empty bedrooms. We are also very diligent about opening blinds to the sun during the day and closing them at night to keep the heat in. We have electric blankets on the beds with flannel sheets that are set on low. DH and I turn it off when we get into bed, but the girls leave theirs on all night. Maybe I should have them share a bed like in the old days.

They'd kill me!
That cut our combined electric/natural gas bill in half last winter compared to the winter before. My family's only complaint is getting out of the shower is aweful cold. I might have to buy two small space heaters for the bathrooms. Turn it on when you get in the shower, turn it off when you get out.
