I've always used this diagram. The little squares with the diagonal lines show the connecting doors. We've had connecting rooms (requested) on 3 trips and they were always in the areas listed on this map. I don't know if anything has changed since the refurbishment, but I don't think it has.

56 & 57 in building 3 are connecting too. I know because I just stayed there. I don’t see the connecting line on the diagram. They may have added it with the refurb.

(We're purposely light packers, so this will be no biggie for us. ) We did pay a bit more for the one night at AoA than our Pop nights, but in the end we're saving at least a thousand bucks on food expenses, so I'm okay with how it worked out for sure!
