Shoreline Keycard West Wing route!

This is a route I use to farm keycards and I just don't have enough people stealing my loot , soo I decided yo share it with you people!
Keys needed:
-West wing room 301 key
-West wing room 218 key
-Office west wing 112 key(optional)
-Office west wing 104 key(optional)
Route:
Make your way to the ambulance and check for a blue keycard(if coming from the side of West Wing check 104 and 112 for a blue keycard first , you can skip ambulance) , after that go to the window of the catwalk between West Wing and the SPA and break the closest window , jump trough it and run to 112 checking for a blue keycard(optional) than go to the staircase closest to the window you broke and go to the basement checking for a red keycard. After you are done go to the second floor and enter 218 , checking for a red keycard , and grab any weapon in the closets. When you are done go to the staircase you came from and go to the third floor , making your way to 301. Check for a LEDX and any loose loot because this is your final destination. You may now kill yourself in any way you want to , preferably a grenade to the feet.
