I'm not able to drive there

Going from New York City to either Philadelphia or Washington, DC is quite easy. If you drive, that's usually the easiest. There's very good train service between those three cities offered by Amtrak (www.amtrak.com). If money is a major concern, the bus is generally cheaper than the train.

If you going to Philadelphia, best way is by taking PATH train to Newark Penn Station for New Jersey Transit's Northeast Corridor to last stop, Trenton which is $15.75 Round Off-Peak Adult Ticket.
When you get to Trenton, you have to go to NJT Ticket Window and purchase round trip ticket on SEPTA R-7.

If you go to Washington, DC, take Vamoose Bus which is $25 each way. Vamoose Bus offers new promotion.
With every tickets, you received a coupon and if you got four coupon, you get on it for FREE!!
Even thought stop in Washington, DC are closed, this bus stop next to Washington DC Metro Stations in Maryland and Virginia, so you could take subways to Washington, DC.
Buses also.

Amtrak goes from New York's Penn Station to Washington and Philly several times and hour.

Washington and its tourist sites are a great deal easier to work with walking and public transit, than Philly's.
