Hotel Booking Instructions for Biomaterials Workshop Participants

We have secured a group rate at the Holiday Inn in Ballston, just a few blocks away from NSF headquarters, where the workshop will be held. The group rate begins at check-in on Monday, June 18th and ends at check-out on Thursday, June 21st. You are welcome to reserve a room elsewhere; however, you will only be reimbursed up to the Holiday Inn rate of $203/night + tax. As the workshop will end on Wednesday, June 20th, we ask that you only book a stay until Thursday, June 21st if flight schedules do not allow you to leave Wednesday evening or if the difference in flight prices between Wednesday evening and Thursday exceeds an extra hotel night.

To ensure the group rate, you must book by Tuesday, May 1st.

The hotel is a 10-minute walk from NSF, but shuttle service will also be provided if needed. Breakfast is not included in the group rate, but the hotel does provide complimentary internet access in guest rooms and the lobby.

To make your reservation at our group rate, please visit this link:

  • Select your check-in and check-out dates.
  • Ensure the “group code” box says “Y29” (if not, please type in “Y29”)
  • Click “view rates.”
  • Ensure the rate of $203 is displayed (if not, please call the Holiday Inn at 703-243-9800, ext. 7120).
    Proceed with the booking.

Please Note: If you are planning to stay outside the window of June 18th to June 21st, you will need to call the Holiday Inn at 703-243-9800, ext. 7120. Tell them you’re with the NSF Biomaterials Workshop and ask for the reduced rate. They may be willing to extend the rate outside the window on a case-by-case basis.

Ground Transportation: Directions from local airports to the Ballston metro station (near NSF and Holiday Inn)

Once in the Washington DC area, the Metrorail is ideal for transportation between local airports and the hotel. Metro is much easier and more cost effective than driving and parking in the area.

Approximate metrorail fares and travel times between Washington DC area Airports and the Ballston Metro Station near the Holiday Inn are listed below. Fares vary by time of day and method of payment (paper cards vs. plastic frequent traveler “SmarTrip” cards). Travel times also vary by time of day

Reagan National Airport $2.50 20-25 minutes
Dulles International Airport $8.00-$12.00 1 hour


Reagan National Airport
The metro serves Ronald Reagan National Airport (DCA), and it is convenient and easy to take the metro from the airport to the Holiday Inn in Arlington. Take the Blue Line from the airport to Rosslyn Station, then switch to the Orange Line from Rosslyn Station to the Ballston metro station. The trip between Reagan National Airport and Ballston Metro Station is approximately 20-25 minutes.

Washington Dulles Airport
From Washington Dulles International Airport (IAD) there are two public transportation options. Details are available at this link: and are summarized below.

  1. Take the Washington Flyer Coach to the West Falls Church Metro station, which is just 2 stops from the Ballston-MU stop near the Holiday Inn. The trip between Dulles International Airport and The Ballston Metro Station is approximately 1 hour. The schedule and fees for the Washington Flyer Coach are available at their website.
  2. Take the 5A bus (departs from curb 2E outside the airport terminal) to the Rosslyn Metro station. From Rosslyn, take the Orange Line 4 stops to the Ballston-MU station near the Holiday Inn. This trip is also about 1 hour. The schedule is available here.

The reliable Metro serves many travelers, so it is common to see passengers with luggage. The Metrorail is considered safe; however, be certain to keep control of your personal belongings while on the Metro. Trains are crowded at rush hour times, so you may wish to use the wider wheelchair accessible turnstiles if you are travelling with luggage.
