I'm sorry for the scare, but you probably over reacted a tad. Depending on how cold it is in your house, your snake should be fine at room temperature for a few hours. The hand warmer is a good idea, but just be careful that your snake doesn't come into contact with it. Hand warmers can get VERY hot and could burn or even kill your snake if it gets too warm. If you do use them, try to wrap it in a towel and keep a close eye on your snake.
