I set up the other trip that Todd posted a link to below.. The price is a little more but we're leaving from Beijing / not Dandong.. but the bonus is it's not a Chinese company trip, this is a guy I already went with last year. I am leading the trip myself, and if you stay on for longer than the four days we'll also be visiting Hamhung (where no foreigners have been before) or Wonson... which is this amazing port town where they take you to the beach and you ended up chilling out with Iranian embassy officials etc. like I did last year... !!!
Message me at alex_hoban at hotmail dot com for any more info if you want it!!
