Do know what the escape rte is in dungeon versus party? I've dragging them around because I have the riding and running perks, but now I have towns so I don't know which is better.Just remember there is a bug where the prisoners given to a friendly (but not owned) settlement are actually given to the garrison (technically a party) and have higher escape rates because of it. If you put them into your own settlement, they go to the dungeon where they belong, it is only the player dumping prisoners into a friendly settlement that is bugged.
