Then it can double as a guest house! Of course there might have to be a lot of cleaning and the "kids" would be giving up their room for the guests. I always had to give up my room when my Aunt was visiting. Wasn't all that often actually.
My daughter has to clean her bedroom and vacate it for a week every December when a friend comes to stay. Easier to move her then the five boys.
When we get the new house built we will be going with a loft room for the boys over my daughter's and the guest bedrooms. The boys will have a private bath. My daughter will share with the guests. The master bedroom/suite will be on the other side of the great room and kitchen.
