Big deal...high end condos and a beach YOU can't go to. Peacocks running wild between golf carts, and occasional people with a look of what are you dong here.
OK so there's a ferry ride there, yippie. You need to know someone or be invited to actually run around there and once you do, that's all. The biggest attraction, besides trying to figure out what these people do for a living, besides being stars is the security they have.
Whenever I am there, I wonder what they do if they forgot to get something at the grocery store...oh I forgot...they don't go to the grocery store.
Stay on the mainland, if you just want to see what it's like there, you probably don't belong there.
