We're doing the JFK overnight thing on Wednesday ourselves for the first time. Jetblue had the best deal out of Detroit by far back when we booked and it required the JFK overnight, but it sounded like fun. We're booked at the TWA hotel, and then on the same 7:30 am to SXM that gets in at 11:30..hoping getting there ahead of the afternoon rush gets us through passport control and to the beach quickly. Thanks for posting your JFK experience, and enjoy your stay Murphycpcu!
