The hospital where Gordon had his surgery only had private rooms and they had a pull-out couch/bed in each room for spouses who wanted to stay the night. It was really a great facility. I didn't spend the night though because of a few reasons. One being that I didn't think there was anything I could do to help hubby at that point in time. I figured he needed to get as much rest as he could but that if I was there all night he would be trying to stay awake to visit with me. I also thought that I should probably get all the rest I could as well before he came home because then it would be my turn to be the full time 24 hour a day nurse!
I stayed late and made sure he was allright and then left and came back early the next day. After the surgery it seemed like he was extremely tired and mostly just needed to sleep off the anesthetic. Of course it is a personal choice and if your driving very far that would certainly be a consideration.
It's important to take care of yourself and get the rest you need too so you'll be better able to help him when he comes home.
Wishing the best for you both,
