IMHO you should stop fretting over crowd levels so much. They simply are what they are while you're there. Go with the flow and soak up each moment whether you are in line for Test Track or shoulder to shoulder with 10,00 of you newest friends on Main Street waiting for Wishes. Follow your heart and go where you WANT and don't let the potential crowd levels steer you away. BTW, MK at night is my fave...
