Not happy that I had to wait outside the hospital ...

Not happy that I had to wait outside the hospital because I had two minors. I went to visit a family member after 8pm with two children and I couldnt go in to visit. I had to wait outside with the kids. The guard stated that this is the policy, but when I checked the policy it states that kids under 18 couldnt go into the room. It doesnt state that kids cant wait in the lobby. I was not happy that I had to wait outside the hospital. It was not hospitality.
