Friends,

I am heading for a week long road trip (Monday to Friday) in the first week of September. It will be a round trip from New York.

Initially I was thinking of New York to Niagara Falls and back.
But what to do and where to stay on the way for nightlife and/or cool things to do or see?
I would love to see a National Park, I would love to get a water sport in.

Alternatively I have heard a lot about Atlantic City and Delaware as cool places to visit and would consider a southbound trip instead.

Could anyone please advise or even suggest great trips 4-500 mile max round trip from NY.

Many thanks in advance, mo chairde.
