How many days are enough to visit NYC, Boston, and Washington DC all together?
2 days in Washington (check out the Smithsonian museums, Vietnam Veteran’s Memorial, Washington Monument, the National Zoo and subway it over to Arlington National Cemetery) 3 days in New York (TOO MUCH here in various places…Times Square, Statue Of Liberty, Empire State Building…the “waterfalls” exhibit going on….plenty more!) 2 days in Boston (downtown area, Cambridge/Harvard) One week should do it!
