Travel
If you're coming from Massachusetts/New England:
We suggest avoiding traffic and taking the Cross Sound ferry from New London, CT to Orient Point, NY. You can find a schedule here: https://www.longislandferry.com/
If you prefer to drive the whole way, make sure to take toll roads into account!
If you're coming from JFK (or other NYC airports):
The Long Island Railroad has trains into Riverhead. JFK has an air-tram into Jamaica Station, which connects to Riverhead. Once in Riverhead, you can Uber/Lyft around the area. It's about a 2 hour train ride from NYC, and if you're up for some bouncing around, find the schedules here: http://lirr42.mta.info/schedules.php
If you are flying in, we suggest renting a car. You will have a little more flexibility and can enjoy the drive out to and around the North Fork.
Hotels are booking up quickly, so consider booking your stay sooner rather than later. We do suggest Airbnb's and VRBO's, as those might be less expensive per person.
