Signposts such as those provided on hiking paths in the Swiss Alps, which show the correct direction and hiking time to all other locations.

The following rule appends a paragraph to every room description. We need not worry about doors (despite the pass in the Bernese Oberland known figuratively as the "Little Door").

"Hotel Stechelberg"
After looking:
   say "Yellow arms on the signpost point:-[line break]";
   repeat with destination running through interesting rooms:
      let the way be the best route from the location to the destination;
      if the way is a direction, say " [way] for [the destination]: [number of moves from the location to the destination] Std."
Hotel Stechelberg is a room. "The wooden hiking inn at the end of the road, with flowerboxes, canton flags, outdoor tables and a triangular paddock for the cows contesting the annual Miss Stechelberg competition. Otto and Marianne do cheerful innkeeper things, while the sun blazes from a gentian-blue sky."
A room can be dull or interesting. A room is usually dull.
North of Hotel Stechelberg is Trummelbachfalle. North of Trummelbachfalle is Lauterbrunnen. Lauterbrunnen is interesting.
Southeast of Hotel Stechelberg is Trachsellauenen. Trachsellauenen is interesting.
