I recently spent a week in a hotel room while my DH had surgery. I did take several books, some hand sewing, my laptop, some office work, and my christmas thank you notes to write. I got all of it done. There is only so much time you can sit in his room and look at him. The rest of the time if I had not had work to do, I would have emptied the vending machines.
Good luck and prayers for both of you. It will be over soon.
