Most parking lots in Saskatchewan have plugins for your vehicle, I would imagine it would be the same in Alaska.
Battery blankets are often neglected. I don't think they would help with FE but sure make cold starting easier and prevent battery damage from the cold. Whatever you do make sure not to drain your battery as a weak battery will freeze and die really quick in the winter.
Block heaters will obviously make it possible to start your car and aid in warmup.
Engine blankets and cardboard grill block will help with warm up and retain heat better. You will also get less ice buildup on your hood when you park.
