I don't know how to post photos. Sorry. But we enjoyed the 877 balcony IMMENSELY last month. We'd book it again in a flash on a view trip e.g. Alaska. Some vibration was apparent while underway. But I noticed it only when the subject was brought up. It did't bother either of us one bit. It wasn't strong enough, say, to rattle glasses. THAT would have been a bummer. Hope this helps.
