One of the biggest reasons we bought our home is because it has a guest room. And as long as there is a free bed, I have an open door policy with visiting relatives. When my parents or in-laws are in town, I look forward to seeing their suitcases roll in as they get to see more of their grandchildren. But, for the sake of space, schedule, privacy or personalities, not all families want their relatives to bunk up in their abode. What's your situation?
