Though mine was only one on side, here is how I handled my travel home from S.C. to Idaho, which was about a 12 hour affair. After the two nights in the hospital, I chose to stay an additional two nights at the Residence's Marriott about three blocks from the hospital. Note that there are two Marriotts near the hospital. The Courtyard, which is across the parking lot from the hospital, and the Residence's, which is about three blocks away. My wife stayed in the Courtyard while I was in the hospital, because it is slightly less expensive, and a short walk. We moved to the Residence when I got out of the hospital, because it has a kitchen and a nice little living area. Both have handicapped toilets, etc, if you request it ahead of time.
I found the trip back to be pretty easy, with the following tactics. We flew out of Columbia, so there was very little time in a car. We arranged for wheelchair assistance at all airports, so that part was very easy. We flew in first class seats when possible, which was a first for me, and very much worth it. I was sure to stay up on my pain meds, and was never particularly uncomfortable during the trip. I did have to use the toilet on the plane, which was incredibly awkward, but doable if you kind of prop yourself up with your hands, and sit kind of sideways so that you do not have to bend too much. It worked, and I did not have to violate any bending restrictions. The only real downside to the travel, was that I had a lot of swelling down in my foot and ankle, from sitting up for so long.
One other thought; I had a difficult time putting my full weight on my new hip, for a couple of weeks. If I had done both hips, waiting a bit longer to travel might have made sense. It sure is good to get home though.
