With that age group I still feel Washington has something for everyone. The Newseum itself covers every age group, something for everyone, even you adults. I cannot stress enough what a great place that is. We went there on Pesach and were looking for drinks. One of the heads of the dining area asked what we need. We explained Pesach restrictions and she went and brought us all (us, kids, grandkids) water bottles - Poland Spring. One of the museum personnel mentioned to us that there was a 911 exhibit and it's incredible, as if you were there. I explained to him I was a first responder over there (Hatzoloh Paramedic) and the building fell on us and he went into shock. The aquarium on the way was very nice too. By the way I am very far from being a museum goer but the American Museum of History was plain WOW. Then again, from NY its a good four hours.
