I took the test last October (canceled), so I know exactly where I'm gonna be at and what it's like to take LSAT there.
Also, it is in my UG college and I probably spent at least a quarter of my college life in that building.
However, for the February test, I've been practicing in that exact room every Saturday to make sure I feel comfortable.
I don't think over-comforting yourself is stupid. I think it's actually better than knowing vaguely or nothing about the test center.
Over-comforting yourself is a bad idea because actual test day conditions will be out of your control and stressful in an environment with a bunch of stressed out people, several mundane tedious procedures you have to go through, and proctors watching you.
Getting used to the room when nobody else is there does not simulate test day conditions.
The purpose of visiting your test center ahead of time is to make sure you know how to get there so you don't get lost on the road test-day morning, know where to park, and know where the building you check-in is at. That's it.
Any behavior beyond simply figuring out directions qualifies as being obsessive/neurotic and automatically deducts 5 or more points from your test-day score since you're likely to be the type that will panic on test-day and screw up somehow. Heck, test day security procedures are almost if not more strict than DHS and airport procedures to board a plane and fly somewhere.
Timed practice tests leading up to test-day should be taken in harsh conditions, not comfortable ones since things will not be feeling very comfortable on test day, no matter how great of a desk you have or if you've become acquainted with the room.
