Carnival is defintely comming to NY next May-October to sail the caribbean. I haven't booked anyone on her cruise yet.
Parking in NY is easy. There is a parking lot right next to the dock. you can see it from the ship. Don't know exactly what they charge. You can call carnival and ask what the cost of the parking is or they will give you the name of the parking lot company so u can call yourself.
