I spend some time looking for the answer online, but could not find the answer.
My wife and me will visit DC for 4 nights. We are staying in Falls Church, which has a a metro station (Orange and Silver line)
We plan to go into the city every day.
What would be our best option to go in the city if we would like to go by metro?
Buy a day pass?
Buy a single fare ticket?
Get the plastic card and put money on it?
