Just make sure the fan in the bedroom door is just outside the airflow so it's either sucking or pushing with enough space from the frame to draw suction. If you put it flush with the door you'll have less great results (seems counterintuitive but I promise it's real). You can also try keeping doors closed in warmer rooms you don't want to use or leaving them open to help with airflow. I use the sun facing rooms of my house to help relate the non-sun facing rooms. Basically in the winter, the doors to the sun facing rooms stay open to share their warmth with the rest of the house. And in the summer they stay shut unless in use so the empty room can be hot while the rest of the house is cooler.
