I am planning on going to erlian by train then taking a jeep across the border. The town right on the other side is Zamyr-Uud. I have been looking and just seem to not be able to find any Hotels online for this town. Has anyone been there and would be willing to give me some advice on this. I only wanna stay for one night or so.

Also, To get an exit stamp how long do I have to stay out of China?
