Yea, that balcony viewing area is a really small space, and I think it was built for celebrities/higher ups from Comcast in mind, not general public. Small gatherings and private events can be held in that second floor area, but I don't think there's enough room for very much guest flow, even if paying lots of money as individuals, to be worth the effort of manning it with staff, etc.
I like Cape May. Gimme lots of clams and I'm, well, happy as a clam.
