Visitor Information:

From JFK: It is highly recommended using JFK airport. Use the Airtrain at JFK to Jamaica Station. (Before exiting Airtrain station at Jamaica, you need to purchase a ticket, which contains 5 dollars for Airtrain and LIRR train fare to Port Jefferson or Stony Brook. (Check the timetable at Long Islands Rail Road or paper copies of it at the train station to determine whether it is a peak or off-peak.) At Jamaica Station, take the train (Long Islands Rail Road) towards Port Jefferson (which may appear as a train to Huntington or Hicksville, check the timetable). Note that you may need to transfer at Huntington or Hicksville indicated on the timetable in order to get to Stony Brook, but it is very easy. Stony Brook Station, next to the campus is the last stop before Port Jefferson Station. If you stay on the campus Hilton Garden Inn, you need to get off at the Stony Brook Station. It is recommended that you contact Hilton Garden Inn in advance (e.g. the day before or on the morning of travel) to arrange a pickup from the Stony Brook Station. It's about 20 minutes walk and there are campus busses looping the campus (see map here), but not as convenient as the arranged pickup. If you stay at Danfords, you get off at the Port Jefferson Station. You may need to call in advance to arrange a pickup or take a taxi to your hotel. It's about 15-20 minutes' walk. (Visitors usually stay either at Danfords Hotel at Port Jefferson or Hilton Garden Inn on Stony Brook campus.)

From LGA, you can take a taxi to Jamaica Station, then follow the above instruction to Stony Brook or Port Jefferson. Or you can take Q70 bus from LGA to Woodside station of LIRR (http://www.mta.info/news/2013/09/06/fly-laguardia-lirr) and from Woodside you can get to Huntington (via the Ronkonkoma line) and transfer to one that goes to Stony Brook (Port Jefferson line).

From New Havens, Boston or north east by train: take Amtrack to Bridgeport, CT. Go to the ferry terminal, take the ferry from Bridgeport to Port Jefferson. The Danfords Hotel is right next to the ferry at Port Jefferson.

From Danfords Hotel to Stony Brook, there is a hotel shuttle. Ask the front desk the night before to arrange. Usually there are visitors to Simons Center using that shuttle service as well. The shuttle driver knows Simons Center. YITP is at the 6th floor of Math Tower, next to Simons Center.
