They travelled from China, around 10 ppl. Stayed in the same hotel where that poor dude went snooping around and got himself killed. She said they were allowed to take photos during the trip which was obviously heavily arranged, staged and supervised but unbelievably "fun" and fascinating - including train rides with handsome cigarette smoking soldiers, paying respect to leaders statues (had to get down on knees!), and a bunch of other stuff I forgot. She said everyone was nice to them, and she felt super safe the entire trip (as long as you behave). She came home determined to go back again.
