Yeah I agree with jim.... no paths contain extra locations... only the different modes (gameplayers versus entertainment) contain different locations... Gameplayer mode containing a couple of extra locations, the most notable being the Mayan Fire Chamber.
Is it? That one escapes me. I remember that if you pick up the brown piece of paper when on path C and go back to the fuschia flamingo there's an extra cut scene, but that probably doesn't count.
