First, spend five gruelling hours filling out applications. Then walk through the maze of doors to get to the correct office. Now attach your pully, safety line, and backup line to the zipline (if you are missing any of these things, please return to step 2f) and hold on tight on the way down.

Once you reach the bottom, wedge open the doors and procede outside. The convenience store is right across the street.
After finishing your purchase, feel free to take the $2 shuttle service back to your room. What, you don't understand why you couldn't have taken the shuttle service down in the first place? It's because you got the economy class room, cheapskate.
