Description

LOCATION: The meeting will take place in the lower west room of the historic UVA Rotunda: https://rotunda.virginia.edu/lower-west-oval-room. For those not familiar with the UVA campus, maps are located here: https://www.virginia.edu/maps.

HOTELS: There are many hotels in the C'ville area to pick from. Some nearby options that would let you walk to the Rotanda are: https://www.marriott.com/en-us/hotels/chodt-courtyard-charlottesville-university-medical-center/overview/?scid=f2ae0541-1279-4f24-b197-a979c79310b0 or the https://www.graduatehotels.com/charlottesville/. But their are many more, so please do a search to find the option that works best for you.

PARKING: If you are at an nearby hotel, walking or an Uber/Lyft is an easy way to get to the Rotunda, though there is a parking garage located about a 10 min. walk from the Rotunda. NOTE: There are also some small private lots located nearby that can be found via Google/Apple map search.

Central Grounds Garage: The Central Grounds Garage is conveniently located under the University Bookstore at 400 Emmet Street, and is near Newcomb Hall, Memorial Gymnasium, Brown College, and the Clemons Library. Hourly parking may be paid via the ParkMobile app.
