Yup, only certain hotels are allowed to book foreigners. I tried to buy my way in once, along with some local friends' help, and we couldn't do it. I got the impression the government would shut them down if they accepted foreigners. The staff seemed friendly and understanding, and there was this "nothing I can do" attitude about it. After walking to multiple hotels in the area we gave up and slept on a friend's floor. I forget exactly where we were. It wasn't a well know city, yet it wasn't small either. I was quite surprised at the time that even with my passport in hand I wasn't allowed to stay anywhere there.
