There were only 2 lounge chairs on deck 7 aft last November compared to around 12 in Feb 2014, so it seemed that they weren't keeping it up as a public area as much as they used to. Also, it closes at night - I think the sign says 7:00 pm. I don't know that there's a specific announcement, but I think that it's likely to go away after the Nov 2016 refurb like it did on the Magic after its refurb.
