Excellent, I thought that sounded rather strange. I read this on an older posting titled Galaxy questions/answers. All it said was that the balconies could be seen. And I couldn't visualize how that was possible unless there were no roofs. Thanks so much for the clarification, it makes more sense now.
I found another funny posting on Cruise-critic. A woman was on her honeymoon and was having an intimate engagement on the balcony with her new husband. Afterwards they sat there for a while naked. Later on they discovered that their balcony was visible from the restaurant above. But she didn't mention the ship she was on. Not that I was planning on doing this, but it was something I would definitely want to know about ahead of time.
