No, it's closed.
No
From the last visit, about 20 minutes before closing time at least two employees kindly told us that closing time was soon. No one actually took us out. It makes me think they want everyone out by closing time. The same thing goes for the souvenir shop you aren't allowed in anytime near closing time.
Sometimes there are special events after regular closing time, some of these special events are for members only and some (very few) allow non-members. I am guessing this is not what you meant, but that'a the best you can hope for I'm afraid.
