Can anyone advise a good, interesting itinerary for 2 adults and 2 twenty somethings Sept/Oct. We would like to visit Rhode Island,, Boston, Ithaca, New York and possibly Niagra Falls but also build in some rest days where we're not travelling. Happy to mix taking the train with hiring a car. We have been to NY before but none of the other places. Is it worth visiting The Hamptons?
