Top floor: through the sanctuary, all the way down the hall, turn right down hallway, on the left. To avoid the sanctuary (because a service or something is going on), go in the left entrance upstairs and go down the stairs, then follow bottom floor directions. Bottom floor: there are a couple entrances to the bottom floor, but if you can find your way to the hallway with the "labyrinth" and go down that hallway towards the elevator, you turn right down the hallway and it's on the left. From the stairs described in the top floor directions specifically, just go straight down the hallway, through the door, and down the hallway to the right, then same directions as described earlier.
