When I was in the Navy we practiced egressing our berthing spaces with our eyes closed. You had to be able to get up to an outside deck as fast a possible. Once you had your favorite route down, then you had to try alternative routes. I still do this today. I never thought about it until I read this thread, but try it. Count the number of stairs and turns and practice. Some of us do our best work in the dark <img src="/images/graemlins/wink.gif" alt="" />
