Basement Maze

For Lab today I had to find a mysterious room in the basement of the engineering building. I went down there and followed a guy who I thought was probably headed to the same place. Unfortunately all the hallways look the same and he was lost too. We wandered a little and then came across a professor and I asked him where to go. His directions were extremely confusing. He said to go all the way down the hall, around a corner, take the elevator, press the button with the W on it, go up half a floor, then go around another corner and the room was over there somewhere. Three of the elevator buttons had W's on them. We pressed one and thankfully guessed right and somehow got there only about 5 minutes late. I didn't think a map would be necessary to get there but apparently there are 2 basements and they aren't really connected. Maybe engineers should have designed it.
