We were on the golden in march and are going on the grand in april. the 20th to be exact.
In march we had 2 "AA" cabins with friends next door
I called the cabin steward and he had the divider opened.
The only thingis it looked like only every OTHER divider could be opened, not really sure if BOTH sides can be opened.
As far as "AA" vs "AD" goes the only differance is the location on the ship( aft, mid .....)
Hope this helps
