"Visitors"

Just a point about patients visitors. I am pleased that there is a rule about two visitors per patient. Yesterday when I visited my father with my husband and teenage son, the nurse told us only two at a time, so that's what we did. But in the bay with five other patients I noticed it was quite crowded and every patient barring my Dad had between 3-5 visitors. A rule should be kept. One group of women visitors were blocking the doorway and medical staff had to walk around them, why weren't they told only two visitors!
