Weird nitpick I know, but I feel like the worst-case wait times on the elevator could be improved. If you just miss it on the first or last floor, you're left waiting for minutes at a time.
I suggest that tweaking the routing miiight help that a bit. Instead of going 1-2-3-4-3-2-1, the elevator could start at the top, go stop by stop to the bottom, then go all the way to the top in one go for 1-2-3-4-1-2-3-4. Then you could have some fun flavor like the elevator that always descends, too.
Bonus points for swapping the two middle stops in the route (so, 1-3-2-4) so that wherever you get on, the next stop will be in the opposite half. That one is cool to me as a very particular kind of nerd but probably unintuitive.
