I'm planning a trip to USA with a couple of friends. We will arrive in NY 2 march13. We plan to travel around there till 14 march before flying to SF. There, we'll do a west coast road trip.
Our general idea is to stay at NY for 4 days. There we plan to cover:
-broadway + timesquare
-the empire state building
-sport event in MSG: maybe the new York ranger
-niagara fall (day trip)
Then boston for 3 days.
Now we'd like an advice on which other cities to visit for our remaining time.
We're interested in Chicago, but afraid it will be too exhausting and expensive to fly there. Any suggestions are all welcomed!
Thanks in advance.
