There is a train station right in Greenport, however the winter schedule is not posted yet, so keep an eye on the train times as they big day gets closer. If it works with your schedule it's a perfect option because it is minutes from the wedding venue and any accommodations.

(Train from NYC-Penn Station to Greenport is 3 hours, no transfers)

(Train from Ronkonkoma to Greenport is 1.5 hours, no transfers)

Hampton Jitney (Bus)

https://www.hamptonjitney.com/booking/jitney/schedules.php - Eastbound, North Fork Line

This bus will take you right from any airport, all the way to Greenport for under $50. It leaves the airports 4 times a day and is an approximate 2hr ride.

**If you're planning on renting a car, remember... driving from JFK/LGA can be intimidating, but it is NOT in Manhattan, on city streets. GPS will be helpful and once you get out of Queens, it's a straight shot. If a girl from small town Wyoming can do it, you can too!
