@threerrr3,
As I read through the recommendations by other transplant patients, I can sense that you are going to be the best prepared patient in the transplant department!  I like all of these suggestions because they don't add bulk to your suitcase.  One small item that I found helpful was a package of ear plugs which were handy for getting a nap or some sleep on a busy hospital floor.  
@des46893,  Pill organizers are the handiest thing ever!  When I received my transplant, my husband purchased one in the patient medical supply shop at the hospital.  I would like add that an alarm on phone or watch is a good way to keep up with medication schedule.  
@danab,  Great reminder about the phone charger!  
@contentandwell,   I could not have used a fleece jacket because it would not have fit over my IV's.  I settled for the ever stylish hospital gown and robe (I'm not sure that all hospitals have robes, though)  Sometimes a gown frontwards, and another one backwards does work though.
@cmael,  I remember being so embarrassed when this happened to me.  I wanted to apologize to my nurses, but they said have none of that.  I think that the nurses and aide are unsung heroes.
@jolinda, I didn't know there was an option for direction of the incision.  
@threerrr3,  Will you share this information with your sister?  
       
@threerrr3 @rosemarya Rather than a light weight fleece jacket, perhaps a baby blanket or shawl to throw over your shoulders. I can see where a jacket might intrude with I vs.
