Sure. If nothing else, they've got labels on 'end 1' and 'end 2', and the rest of the boat is labeled into quadrants that don't change (A-D). If there's a galley, that's on one end or the other; the passenger deck is assymmetric.

The car decks and the sundeck appear to be mostly symmetric other than labelling, and maybe elevator placement? The machinery under the car decks is likely somewhat assymetric too, but I've never gotten to go down below.
