Almost always, they have set up the house to keep you from wandering through the private parts of the house on the way in and out. I've only stayed in a few, but they always had a public living room and dining room which you access through the public entrance. The staircase to guest rooms was also in this area. A single (closed and marked) door lead to the rest of the house, which most likely has it's own living room for the family.
