You will not get any insight into how local North Korean people live. Your tour will be highly choreographed to visit only authorized sites, shop in approved stores, and speak only to official guides. Do not break any of the rules of the tour; doing so will place your guide at risk. He/she will be subjected to imprisonment and even torture, for assisting your "espionage". Do what the guides do, praise every stop on your tour, and remember the rule, "If you have nothing good to say, don't say it at all."
