I can report on 4 rooms.
469...lock-off studio: beautiful view of Spaceship Earth, nice sized balcony. Good view of top of Illuminations, too.
525...view of the wetlands, smaller enclosed balcony. Great view of top of Illuminations I was told.
430...one bedroom lock-off. Tiny balcony (but better than the standing ones at BC that Terry alluded to) off living room, no balcony off master. Quiet pool, accessible room.
428...studio lock-off to 430. Same type of small balcony as 430.
