I hope you don't mind me jumping into the thread :-)
I found this thread by doing a search for Seoul, and I have been looking for a smart way to go to the DMZ and this looks perfect!

Instead, I'd recommend taking the DMZ train. Muuuuuch cheaper and it's run by KORAIL, the train operator for the country. They also provide a Dorasan National Security Tour to the tunnel and observatory. The tour and tickets can be booked at Seoul Station.
