(adsbygoogle = window.adsbygoogle || []).push({}); like everyone else who posted the strategy of on the balcony. This is mine.
-1 person watching window & on ground
-2 people watching from the top of balcony to the ground
-1 person watches the stairs(just in case if some get through).

My other strategy
-When you start theres a door on the left. and theres only 1 window to watch
-1 person watches window, then 3 people watch the entryway.
-i got to 34 this way.
