Wise travel people - We have 16 nights flying in and out of JFK in July - DH and I, DCs aged 8 and 11. we have all been to NYC and love it, kids haven’t been to DC before and would love the museums and the Whitehouse etc - but where else should we go? I was thinking it would be good to have a bit of beach time - Montauk? And some mountains - Shenandoah? But generally v open to suggestions of places we might enjoy - historic, nature, wildlife, Americana, or just cool! Assume we will hire a car outside of cities, but would also consider the train. Kids are good car travellers so long distances not a problem though we have found it’s best to not have too many single nights in places…
I spent a Summer in Maryland on a summer camp about 25 years ago and definitely went all over but can’t remember much, bit of a blur!
