You may also want to try remote controlled toys - cars, planes, drones. Controlling them well requires that you be able to transform your position into the vehicle. Beginners tend to turn the wrong way when the vehicle is coming toward them.
Now that I think of it, don't walk around at first. Just face away from a door, look around, then shut your eyes and try to turn around and reach for the doorknob. If by chance you make a real experiment of this or find a way to get better at it, please write about it!
For instance in my case I'm actually better at steering an RC car or similar than I am at figuring out which way I should turn myself. To the point that sometimes when I'm lost, trying to relate a map on the wall to hallways in a building, my best strategy is to step outside myself and say, "OK if there were a mouse in a maze which way would the mouse have to turn here?" Often, the answer I get from doing that is different from what my brain tells me I myself should do; always, it is my first-person reasoning which has it wrong and the 3rd-person reasoning which is right.
Coordination of movement in space (for example something like grasping an object) is more dependent on parietal cortex & the dorsal visual stream (the so-called "where" pathway), and the cerebellum.
"Visuospatial skill", as typified by tasks like mental object rotation, is more ascribable to temporal cortex & the ventral visual stream (the so-called "what" pathway, responsible for object recognition). However, it often requires both ventral and dorsal visual cortex.
Navigation is hippocampus-dependent. However, the hippocampus is not a "GPS". I cannot emphasize this strongly enough. It is a hub for integrating and associating disparate information from across the brain in order to form representations of and the relationships between behaviorally-relevant states. This explains why the hippocampus is also involved in "navigating" abstract state spaces, for example turn-based game states [0] or auditory frequency [1], when they're behaviorally relevant. It gets analogized as a GPS because 1) most of the research involves spatial tasks, so space is the behaviorally-relevant dimension, 2) a certain Nobel Prize winner does not feel the need to update his theory, and 3) "Hippocampus = GPS" is too sexy and intuitive of an analogy, especially for the lay press.
The idea of the hippocampus as an "associative engine" also helps unify its seemingly disparate roles in "navigation" and memory when you consider that a memory is just information from disparate brain areas that's been associated via temporal correlation because of its behavioral relevance. It also explains why researchers observe "place cells" and "time cells" and "head direction cels" and "eye position cells": because these variables are behaviorally relevant (i.e. important for maximizing reward) in the task the animal is performing.

I wonder how much it costs to get my brain scanned.
Yeah, I suspect these are all deeply related. Fascinating.

Sounds like something that could bankrupt you stateside. If you want to get it done cheaply and by qualified people, there's always Eastern Europe :)
Try this experiment and see how you fare. When you're in the shower, imagine that the feeling of the water (preferably cold), is like being in the middle of a fire. Imagine being bathed in the flames. Try to associate "wet" with smoke, dancing flames, no pain in any way. It's surprisingly hard but possible. It almost puts me in a meditative state when I try this unintuitive association excercise.
Anyhow, there are learned separations between observations and qualia. I think the one between time and space is such -- learned, not so much due to actual specialization in the brain's anatomy.
