Suzanne,
I am sorry to say the only handicapped accessible room layout with a roll in shower that I have in my photobucket is the value room layout.
I search many travel websites looking for the room layouts of the different Disney resorts. I have the standard room layouts of all the resorts.
I have many of the Suite layouts (AKL, WL ,GF, CR, etc) and most of the DVC layouts.
I am still seaching for more of the HA room layouts.
Are you staying in HA family Suite next spring?
If so please take lots of photos and post them on the All Star Music Family Suite FAQ thread.
I also need a HA room with a roll in shower and I was not able to get a HA Family Suite during our last trip.
It was not available for our dates.
Have fun at Disney!
