If you ever, for some reason, want to get REALLY REALLY lost, get in a group and go into Stormhold. Close your eyes, let one of your group members run around a bit, count to 100 and then waypoint and try to find them. Good luck!
Also works in Ruins of Varsoon, Vermin's Snye, Condemned Catacombs, Crypt of Betrayal...you get the picture.
