The birthday family receives one parking permit to park in the Museum parking lot on the 4th Street NW side of the building. Please note that our parking lot is first come, first parked, and thus we cannot guarantee parking in our lot even with a parking pass.
After parking in the lot, enter the museum through the 4th Street/Employee entrance, then meet the Museum Teacher at the 4th Street Security Guard’s Desk where you can pick up your permit. Place the permit on the dashboard in your car.
