Anyone know if either of the sky decks close at a certain time like sunset of something? I likely won't get there till 8:30pm as my departure isn't till 11:40pm but keen to go to the rooftop space. Granted it might be dark anyways by then.

Once before I tried to go up to the one in the B Concourse but when I walked over to the sky Deck area in the club, it was closed.
