Your room is the envy of snakes everywhere...Well done!
And btw, what I really do when I take my snakes out varies (depending on the snake & the weather): I like to stroll in my back
yard with them for some natural sun (yard is about 2/3 shade) but I don't put them on the ground (too "buggy" here). I used to
have a "snake-safe" room & let them roam for exercise & a good game of hide & seek, but I no longer have that room & space.
I've noticed that many snakes get very mellow when I sit in a hammock or my rocker-recliner chair with them...even to the point
where they doze off. (admittedly does nothing for their "exercise" lol) And I let them explore my bed or couch with supervision,
or play in their "tree" (on a sturdy vertical stand).
I was kidding about playing chess: they cheat & clear the board with their tails...
