I had something similar happen at OKW on the stay I'm on right now. I booked "near Hospitality House" and I am not in one of those buildings. Granted, it's not a point difference, but it's still not what I booked. I questioned it and was given a variety of answers by CMs as to which buildings represent this category. A manager came over and said that I was correct. He had no answer for why I didn't get my booking category but was apologetic. He offered to move us.
