Travel Arrangements and Reimbursement

Thank you for agreeing to speak at CITP. Please look over the important information below regarding your visit to Princeton.

If you are speaking at a CITP sponsored conference, you will be contacted by the event coordinator regarding your hotel, travel arrangements and the conference schedule.

Travel Arrangements

If you will not be travelling directly to and from Princeton on the dates surrounding your talk and will be combining your trip with other meetings/activities, we will be happy to work with you or another institution to split the cost of your travel.

If CITP will be arranging your travel, please provide the required information on the CITP Guest Speaker Travel Form at this link at least 14 days in advance of your talk.

For air or train travel we can only book or reimburse economy fare or coach class. If you would like to upgrade to business class, you will need to cover that expense yourself. If you choose to arrange your own hotel, Princeton will reimburse the amount that we would have paid had we arranged the reservation. Please keep all receipts, as they are required for reimbursement.

Accommodations – Nassau Inn

CITP uses the Nassau Inn for most overnight stays. The Nassau Inn is within walking distance to campus, located at 10 Palmer Square, Princeton, NJ 08542, 609-921-7500. Click here to view the Nassau Inn’s website‎. Princeton receives discounted rates at the Nassau Inn, so if you are being reimbursed by CITP, a representative of CITP will need to make the reservation for you. If you make the reservation yourself, we will only be able to reimburse up to the amount of our discounted rate.

Walking directions from the Nassau Inn to Sherrerd Hall

From the Nassau Inn go up to Nassau Street and turn left. Walk down Nassau until you reach Washington Street and then turn right onto Washington. As you walk up Washington for about a block or so, you will see the pond at Robertson Hall across the street on your left. Cross the street and walk alongside the pond, down the stairs, and past two brick buildings. You will see an all-glass building to your right. This building is Sherrerd Hall.

Sherrerd Hall

Sherrerd Hall is an all-glass building between Wallace Hall and the Mudd Library. It is located on Shapiro Walk and Charlton Street (which is a dead-end street only accessible from William Street.)

Enter the main doors of the building and walk up the staircase to the third floor. Turn left into the hallway and room 306 will be on your right after you pass the open space area.

If you prefer to take the elevator, when you walk in the main doors of Sherrerd Hall, turn left down the first hallway to the back of the building. Take the elevator up to the third floor and exit veering to your right. Go down the hallway and room 306 will be on your left.

Driving Directions and Parking

Please see Princeton’s website for driving directions to Princeton. If you are using a GPS, enter 35 Olden Street, Princeton, NJ. This is the computer science building, which is to the right of Shapiro Walk, and Sherrerd Hall is located to the left of Shapiro Walk, two buildings from Olden Street.

Transportation to Princeton


The best large airport to fly into is Newark (EWR), as it is easy to get to campus. If you are going to/from the Newark airport, please take a NJ Transit train to Princeton Junction and then a cab/Uber/Lyft to campus or your hotel. We cannot pay for a car service/taxi/Uber/Lyft from the Newark airport to Princeton.

The procedure to get from Newark airport to Princeton is fairly easy: Take an AirTrain (cost about $5.50) to the Newark International Airport NJ Transit Train Station and buy a ticket to Princeton Junction (cost about $17.25).

Please make a note of your gate if you are traveling from Princeton Junction back to the Newark airport. You will need to get on the AirTrain from there, and it stops at all the gates.

Frontier Airlines offers direct flights to Trenton/Mercer Airport from Atlanta, Chicago, Detroit and several other cities, and this is actually the closest airport to Princeton, as it is just a short cab ride to campus.

Philadelphia Airport is also fairly close, but it is more difficult and time-consuming to get to Princeton. If you are going to/from the Philadelphia (PHL) airport, please contact Jean Butcher, to arrange a car service for you. This needs to be pre-approved and reserved by Jean, as Princeton University gets discounted rates. If you choose to book your own car service, we can reimburse you up to the amount of our discounted rate. You can also take a train from Philadelphia to Trenton. Once in Trenton, follow the NJ Transit train directions below to get from the Trenton Transit Center to Princeton Junction and then to campus or the hotel.

JFK and LaGuardia are not cost effective or ideal airports to get to Princeton easily, and we request that you fly into Newark instead. (If you choose to fly into JFK or LaGuardia please note that any car service used will not be reimbursed.)


If traveling by Amtrak, your destination stop should be the Trenton Transit Center or Princeton Junction.

From/to Trenton, take a NJ Transit train from/to Princeton Junction. and then you have two options. You can either take a cab to the hotel or Sherrerd Hall (approximate cost $22) or get on the “Dinky” train (approximate cost $5), which will then take you from Princeton Junction to Princeton’s train station. It is a three-quarter of a mile walk from the Princeton train station to the Nassau Inn. At Princeton Junction you should be able to get a cab without calling one, but if you need to call one, see “Cab companies” below, or use Uber or Lyft.

NJ Transit trains:

The cost of a cab to get to/from campus from Princeton Junction is about $22, Uber and Lyft rides are usually less expensive. NJ Transit trains run from approximately 4 a.m. to 1 a.m.

If you are arriving on NJ Transit from NYC or Trenton, you can either get off at Princeton Junction and take a cab/Uber/Lyft to the hotel or campus, or take the “Dinky” train from Princeton Junction to Princeton. It is a bit of a walk from the Princeton train station to Sherrerd Hall, as they are on opposite sides of campus. The TigerTransit bus service is available from the Dinky station. Please see the TigerTransit webpage for more information.

Princeton Taxi – (609) 672-7072

Car Service/Car Rentals:

If a car service is needed it must be approved in advanced and reserved through a representative at CITP. Princeton receives discount pricing from certain vendors. We do not reimburse for car rentals.

Meals – Receipts are required

We cannot reimburse for any meals that are provided by us or included in the hotel reservation, even if you choose not to use them. For any other meals, please save your detailed receipts*, and we will reimburse you for the exact cost of your meal, as long as it is equal to or lower than the GSA rates for the city you are in. We will not be able to reimburse amounts over the GSA rate guidelines, which for Princeton are: $14 for breakfast, $16 for lunch, and $26 for dinner. GSA rates for other cities will be used if you are claiming expenses for meals in your home city, but again detailed receipts are required. Alcohol charges cannot be reimbursed.

* Detailed receipts are required for meals. The GSA per diem rates are used as guidelines for “reasonable” costs.

Once completed, return the form to Jean at Please include scanned copies of all receipts. Due to IRS rules, all requests must be made within 30 days or Princeton will consider it taxable income.
