Another thing to note about the behavior:
I used to think that more space to roam was a good thing, but a few older keepers pointed out that the more unsuitable a space is, the more roaming a BP will be. This doesn't mean that roaming and exploring is bad, but it CAN be a sign of stress. I think anthropomorphizing the snakes can be a problem. While animals do explore and get curious about new things, sometimes roaming may be a sign they aren't comfortable. For instance, many older dogs get restless if they have arthritis because laying down for too long hurts. It may be good that they are active and moving, but not if they can't sleep well.
No one can say what is going on in their snake's head, but it is something to think about! I think whatever works best for both owner and snake, (as long as the animals are safe and healthy) is the best option!
