I am going to be in Washington DC for 7 consecutive days. I have a couple of questions please:
1- I am planning to buy a SmarTrip card. What are the cons of using such a card?
2- On the website, it is mentioned that the 7-Day Fast Pass is available only on a SmarTrip card. What does that mean?
3- If I am not mistaken, we cannot buy transportation tickets and cards at Dulles Airport (IAD). So if we want to take the 5A bus, we should pay with cash. Now, to go from the city to the Dulles airport, and suppose that I don't have a SmarTrip card, can I buy the bus ticket from somewhere or it is always purchased from the bus driver?
