Cujet here. My wife (mamacujo) posted in this thread, under my screen name by accident. Sorry for the confusion.
She had a private room right after recovery. I don't believe Memorial hospital has any semi private rooms in the bariatric section. I went to visit her in recovery. And after going to the recovery section, I believe remaining there for a while is a very good thing. Everybody there was very attentive to her needs, and it's very well equipped in case additional attention is needed.
Please understand, I cannot answer your questions about the surgery, as it was not me, but mamacujo that had it.
I will say this, Memorial hospital was stunningly clean, the staff was quite attentive and my general feeling about the hospital, staff and surgeon was 100% positive. They let me remain with my wife overnight, in privacy, without question. That in itself is a miracle with today's strict rules.
