Very little of what you mention was obvious to me. From the courtyard forward was the only place I wasn't completely lost all the time.

Before that, the multi-level section around where you get locked in with a knight, the labyrinthine rooms around the kitchen, the rampart tops and rooftops, the outside sections... Everything was pure confusion. Kept coming back to the same places, entering one of the million nearly identical looking doors, going round and round without ever reaching the place I was trying to reach...

Subtle hints don't really suffice for people without a sense of direction.
