See several of New York City's most iconic sights all in one excursion. First, embark on a ferry trip to the Statue of Liberty and Ellis Island; you can admire views of the New York Harbor and explore both landmark attractions with an included audio guide. Once you return to Manhattan, head to the National 9/11 Memorial & Museum; with skip-the-line tickets, you can head inside and spend as much time there as you'd like.
