Condi has surgery, gets the mythical overnight stay

Check out the healthcare package that Condi gets. Considering it was a "minimally invasive procedure" and a fairly routine procedure and since she will be back at work on Monday, how come she gets an overnight stay at the hospital? Don't get me wrong, I think an overnight stay ought to be pretty standard but I've gone under three times for surgery in the US and I have always been pushed out the door pretty quickly, within hours of going under the knife. Women in America often have to play games with checkin times at hospitals in order to get an extra (second) night after delivering a baby because of insurance companies and then I see this. Damn, some people certainly are more equal than others.
