Actually, the monorail runs through the Grand Californian property, but not exactly in the same way that the WDW monorail goes through the Contemporary. When we stayed in a Concierge room @ the GC in January, the monorail track was almost directly below us, a few floors down.
The only stops that the DL monorail makes are within DL (in Tomorrowland) and at the far end of DTD.
