The 1st piece of advice is to speak to "cruise" specialist agency. They have the expertise to guide you through the process. You have chosen to sail, when most kids are out of school, so, factor in lots of kids.
You have to add on port charges and taxes too, for your total price. Cruises from NY, with 7 days, basically only go to the Bermuda/Bahamas...you would need a longer sailing to get you deeper into the Caribbean.
