Okay, I hope to the gods I don't sound really stupid here, but isn't it possible to go thru every door with the configuration given already? I'll try to use ASCII art to demonstrate, but this is the first time I've used ASCII art (I find it a cruddy art form, personally.)

If you follow the Zs from outside to room E, C, B, E, D, B, A, D, in that order (I think)you should be able to get thru all the doors w/out going thru one twice. I hope I didn't read the problem wrong...
