Everyone on the boards have been so helpful so help me decide which is more economical the 7 day weekly unlimited pass and bus pass or buy the fares individually. Here is our situation we are staying at Cherry Hill Campground so we will be using the bus at least once to get to the metro stop. We are going to be in DC for 6 days. I think we are going to go into DC each day until 3pm or so and go back to the RV for some relaxation and eat dinner. Then do the whole situation bus to metro stop and then go into dc for the evening a few days. The 7 day unlimited rail pass is 40 dollars and the weekly bus is 12. Thanks everyone. Cherry Hill Youtube on the metro talks about on the way back you can get a free discount pass to take the bus back to the campground so this is getting too confusing.
