If you are talking about the stairs form the lift hill to the bottom,I don't think the stairs go down all of the way. From what I've seen(don't quote me on this, but)it looks like the stairs go down until they reach the little "safety car". If the steps did go all of the way down, I know I wouldn't want to have to walk down them if I were stuck up there.
