I found some great information on the new port at this link:
http://www.brooklyncruiseguide.com/cruise-terminal.html
It will give you information about the port and how to get there. It's going to be beautiful!!!
I will be cruising the new Crown Princess from NY in July and am looking foward toit.
Also, If you're going Eastern Carrabean, Grand Turk is also a brand new terminal being built by Carnival Cruises!!
