Just a quick comment but the hospital I had DS at didn't have a "waiting room" unless they were going to hang around in the foyer of the main building miles away from the maternity ward. And there was no way the midwives would allow family jsut wandering around the delivery area/maternity area just waiting for some birth - they also warned us to tell our family there was no point ringing to find out what was going on cause they wouldn't be telling - they wouldn't even say if you were at the hospital or not.

Midwives also said that they are more than happy to be the bad guys so if you ever don't want visitors/hangers on etc just let them know and they'll enforce your wishes.

If nothing else works - and please I'm only suggesting this as a last resort - maybe use the old "sorry but your not allowed to be there only x and x in the room with me and that's it - they just don't have the facilities". May not be plausible in all cases - if they know the hospital rules etc but in my case it was certainly the truth.
