Every day, 10,000 people enter New York’s Grand Central Terminal—with no intention of catching a train. They come to slurp bivalves at the Oyster Bar or cocktails at the Campbell Apartment. They gawk at the ceiling embellished with gold constellations, browse shops, and take tours. It’s enough to make the landmark one of America’s top five most-visited attractions.
Location, of course, plays a role, and many of the most popular attractions are found in major cities such as New York, San Francisco, and Seattle. Size, too, matters. While the National September 11 Memorial had an impressive 4.5 million visitors during its first year (it opened on Sept. 12, 2011), it was dwarfed by Central Park with 100 times the area.
