I have Silent Hill 4 and I've been playing the game and solving all the puzzles and junk but now I've finally gotten stuck.

I'm at the end of the Building World Second Time and I'm stuck. To get to the very end you have to go down the ladder in the Elevator and then come back up and go blah blah blah to the end. But that girl that I'm with can't go down ladders and I can't exit the level without her. There must be another route to get to the bar / billiard room so she can come with me, but I can't seem to figure it out. Any help would be appreciated, and also please don't reveal any info past this level! I don't want to be spoiled, thanks!!
