Hi Bossman:
I think it is better to stay one night in Toronto as will be hard to travel after your surgery. I just had a 30 min drive from hospital to my home and still was difficult as I was not even 70% recover from anesthetia. They let you go in few hours. And if you are coming from out of Toronto, I think it will be difficult to take a bus or train. Also, you will have some drainage. So blood all over the place. Your chest will be heavy. So not advisable.
If you have insurence from your work, you can book semi private room as most of company insurence pays for semi private room. Also, you can get private room for just extra $20. I checked with St. Joe and their charge is $190 for semi private and $210 for private. So you pay only $20 extra as $190 will be covered from your company's insurence. I think if you tell them that you are coming from out of Toronto, they may give you overnight stay. I think you should check with Dr. Fielding's office first for that.
