Hi TOS Gerl,
I had surgery several years ago and was released from hospital 2 days later. I stayed an extra night in hotel then flew home (1 hop), 2 hr flight by myself. I have to say, dealing with the airport on my own was quite difficult, even though I planned ahead (knowing i wouldn't be able to lift/carry much) and brought only a small carry-on bag with the bare-minimum supplies. It was difficult navigating through security w/only one arm, not to mention getting around the airport. The airline did let me board first, which saved some hassle. The flight was uncomfortable and I felt like fainting half the time. I know a car ride would also be subject to quite a bit of jostling around, but I would definitely vote for driving (at least now that i realize YOU won't be driving - at first I thought you were going to attempt to drive yourself and was going to say you are insane!!).

It really does make a difference having someone with you when you check out of the hospital, get your bags for you, etc. Plus if y'all drive, you can stop for stretch breaks as needed, if the car gets to be too much.
Best of luck for your surgery! Prayers for a good outcome.
