Since this is a thread "about value":
Right now I can go downstairs and in 10 minutes & $20 be at the Manhattan cruise terminal
Or....I can go downstairs and in 30 minutes and $50 be at the airport (not to mention airfare, cab to the ship..and stress of actually getting there on time)
I understand what you're saying....and if I lived in any other part of New York, even NYC....going to other ports might be attractive. But, one of the reasons I deal with high rents, high crime (lol) and other "high costs" is for the convenience of living where I live.
