JFK is considerably farther out.Last time I flew into JFK, the money I saved on airfare (JetBlue, cheap) was totally offset by the taxi fare into Manhattan, around $75.00 with the tip. Call Carey Limo (they have a national 800 number) and ask them how much limo transportation for 6 will be. Most NY cabs are quite small and you will have to take a few of them to accommodate everyone. A limo will take all of you in much more comfort than a cab. The piers are in midtown Manhattan on the West side, fairly close to the Broadway area.
