There are only three outlets in the surgery waiting room, so make sure your electronic devices have full charges before you get there! Other than that its a gorgeous hospital with wonderful staff!
Note that the ER entrance if you're not in an ambulance is at the very end of the campus, in the least accessible area. Thank them for adding to your stress.
If you get admired, have someone bring your laptop to pass the time, there is Wifi in patient rooms, and with one TV between two people, you might need a distraction from your roomie's soap operas.
