Update: We have blocked a set of rooms at the Key Bridge Marriott in Roslyn, Virginia for $99 per night. Here is the page to make a reservation. The Marriott is next to the Potomac river and a short walk to Georgetown, DC. It is also three blocks from the Metro.
We have created a page for Nicole’s Bat Mitzvah! It is located here. We will update it as we get more information.
