[Part of it was easy enough. The white styrofoam take-out container is fairly innocuous as it sits there, smelling of corned beef and sauerkraut and grease. A six-pack of bottles of Mt. Dew Code Red sits nearby - already chilled and waiting. Tucked horizontally between the two rows of bottles is a rolled piece of nearly-indestructible parchment. It's tied off with a ribbon, like any good treasure map, and unrolling it reveals a layout of the hotel.
Unfortunately, it's not nearly as detailed as he wanted. It includes the layout of each floor, with the rooms clearly labeled. Many of them are simple room numbers, but where it's needed, the door is labeled with a name. And only a name. If a person watches the map long enough, some of the labels will shift, switch, move to a different wing of a different floor. Every door has a label, and every label is accurate. Always.]
