You may also want to look at the HamptonJitney. I know they go to greenport and assume they have a taxi connection with Islip as they do for the South fork. www.hamptonjitney.com

Interesting but the Hampton Jitney doesn't have an ISP stop to the North Fork. YOu could phone and ask though.

Simplest would be to take one of the car services. I've used Colonial and they're fine.

Depending on how many you are, the cheapest option would be to take a shuttle to the Ronkonkoma train station (Colonial runs a shuttle for $5/person to the train station which is about 10-15 mins away) and take the Long Island Railroad to Greenport. The train trip is about 1 1/2 hr. but the trains don't run very frequently.

Will you not need a rental car when you get to Greenport?

I thought the North Fork Express bus made a stop in ISP....
631-588-RIDE

Ignore my post....it looks like NFE not only did not stop at Islip but that service has been suspended on all routes! Ooops!!
