Narrative:

Ground control instructed taxi to runway 7 hold short of runway 11 approach (has red sign indicating runway 11 approach). While holding short of runway 11 approach; tower instructed to taxi to runway 7. The taxiway curves from that point and without being familiar; it is almost impossible to determine from the NOAA airport diagram that there is or is not an additional holding point. As it would not make sense to issue a taxi clearance past that point unless there was another holding point; pilot assumed as much. Runways 7 and 11 begin almost at the same point; however there is access to runway 7 without crossing runway 11. In addition; controller changed runway assignment twice. Began taxi past runway 11 approach point and noticed runway edge markings of runway 7 and aircraft on short final. Stopped prior to runway incursion but feel that this is a very dangerous situation. ATIS has standard message about read back of hold short instructions; but no mention of this specific safety issue. Nothing in notams.
