I am working with two gentleman from India who do not have access to a car and would like to get some sightseeing in while they are here in Baltiimore. They will be in the Greater Baltimore area (Owings Mills) for a couple weeks. I am not a good tour guide so I was wondering if anyone can suggest how they could get into DC for the day via the train and what tours they might have access to. They are able to take the MTA bus to the Metro that is along 795 via bus - so how would the get to DC from there? Also, if there is a nice hotel that is not too expensive, they might be able to extend the trip into two days. Suggestions on all are greatly appreciated!
