I watched WISHES last year from The Plaza Pavillion. I vacation solo, so it is often easy to squeeze in one extra seat somewhere. There was a decent table right along the railing where one person was seated there. She was not eating or anything like that. I just walked right in and asked " Are these seats taken?" She said "No", so I just said "Thank You", and parked my butt.
She was not particularly friendly, though, and no other people came to join her. The view was really great !
