I agree with all the points that @erie-herps made. Bags in boxes for snakes, small containers for lizards, keep the dimensions rather snug, and make sure you have air holes. You know the size of the containers that reptiles are displayed in at reptile shows? You don’t want to try and transport them in anything with too much space- think more along the lines of those deli cups at shows. I wouldn’t feed them for at least a few days before the move, perhaps longer for the snake.
