New York, Boston, Washington DC, Niagara falls - the transportation
After the Eurobasket I'm going to New York and will stay around for almost a month.
I'll be without a car (I have a driving licence, but I afraid to drive alone in another country and it is probably expensive for one person alone), so I'm trying to plan the trip according to the public transportation.
I think that most likely I'll visit Boston (and Cambridge next to it) and Washington DC.
I would also like to see the Niagara falls (U.S and Canada), and regarding this I'm uncertain about several things:
1. Is it conveniently reachable from Boston and Washington, so that I could do NY->Boston->Niagara->Washington instead of going to all the other 3 destinations from NY and back.
2. are the organized tours there advisable if you are without a car.
3. Should I maybe visit some cities in Canada on the way or not far from there. I don't know also how much time I'll have, but I would like to know if something is highly recommended.
Any other advices are appreciated as well
