I was in room 560 in early July. This was a studio and it also had the giant balcony. You could fit probably about 20 people out there!! I looked out over the quiet pool and it was a great view in the daytime. At night, there is a large bright, and I mean bright, light on the balcony that will not shut off. It prevented me from sitting out there and that is something that I normally always do at night. All the balconies may have this, not just 560, but I can't say for sure.
I don't know about the Epcot side, I did take a peek while housekeeping was cleaning a one-bedroom, but that one did not have a large balvony and I didn't see that side of the hotel from the outside.
