Here in my hostel in Beijing there's a European couple who want to travel to Dandong, which is a city right on the North Korean border.
So Wikivoyage lists some suggested places to stay but, along with all the places in their Lonely Planet, none of the places will accept bookings from foreign guests.
Obviously this is deemed a sensitive area. But also obviously it was recently possible to stay in places listed in the aforementioned travel guides.
Are there some known hotels or other accommodation in Dandong which have permission for foreign guests to stay, or is the whole city now off-limits to tourists who wish to stay overnight?
If it's really not possible to stay in the city right now, the closest place nearby where it is possible to stay would also be of interest.
