The section of the resort that is closest to Bay Lake has the solid balcony walls on the 6th floor. So, I believe that 6113 would have the solid wall and 5113 would be the regular, open balcony. The section of the resort that is closest to the lobby has the solid balcony walls on the 7th floor. I really don't know whether 6131 is in the section of the building closest to the lobby or not. But most of the 5th floor rooms throughout the resort have open balconies. There are a few scattered rooms that have the solid balcony walls on lower floors, so you should just request the open balcony to be safe.
