Hi, CoralS.
I would very much second Fr. Pat's advice about loose clothing. My center never mentioned it, but LDO had prepared me. Had I not taken sweat pants with me, I can't imagine what I could have worn home.
Also, I was very sensitive to bumpy rides for quite a long while after donation. I don't have a car, and had to use lots of taxis, rather than buses.
I remember that I had hoped to jump out of bed and start walking as soon as I could after surgery, as at least one LDO poster reported doing. What actually happened the day after surgery was that I spent hours (I think) staring at the walls before it even occurred to me that I could try wiggling my fingers and toes. Not that I was paralyzed or anything--it just didn't occur to me. I also slept quite a lot, I think. What finally got me out of bed was having to use the bathroom. It took a while before I braved the muscle pain involved, but necessity is the mother of invention, I guess, and I finally hit upon a sort of scissor-kick motion that helped me swing my legs off the bed and get on my way.
Check with your center about the exact length of time, but be prepared to avoid lifting (even not very heavy things) for a good while; I found that even opening heavy doors was difficult.
I wish both of you successful surgeries and speedy, complete recoveries!
Be well, Snoopy
