My girlfriend grew up a few blocks from coney island and her parents still live there. Unless you are a New Yorker and are used to these kinds of neighborhoods (trash, graffiti, crowds, VERY odd people wondering about) then you may go. Very few people would bring their families from far places let alone the NY NJ suburbs to this spot. Disney would be foolish to even think it. Imagine the Belt Parkway even more crowded then it already is!
