How do I navigate the maze of passages, all different?

Hint 1 of 4:

The names of the locations are subtly different.

Hint 2 of 4:

By making a grid and noting where each direction leads from each location,
you can build a map. It's a hassle, though.

Hint 3 of 4:

Actually, you don't need to go into this maze to finish the game with all the
points.

Hint 4 of 4:

I haven't mapped it all out myself. From the west end of long hall, you can
go 'south, east, west, south' to get to the vending machine.
