Washington, DC, garners its fair share of travel press this time of year because of soon-to-bud cherry blossoms. But don’t forget about that other East Coast history hot spot, Philadelphia. Home to one of two U.S. Mint facilities open to the public (Denver is the other; www.usmint.gov/mint_tours), families can take an hour-long self-guided tour of this money manufacturing plant. Unfortunately, they don’t give out freebies. Diagonally across the street is the home of the Liberty Bell, set in a $12.9 million glass pavilion. This tour is also self-guided and free, but guides are on hand to answer all of the children’s questions about that crack. Stay at the Sheraton Philadelphia Society Hill Hotel and you can walk to other Old City attractions like Franklin Fountain, an early 20th-century soda shop that makes the best root beer float I ever had, and Shane Candies, the oldest continuously operating candy story in America. Save room for dinner at City Tavern. A reconstruction of an 18th-century tavern where Ben Franklin and other Founding Fathers dined, waiters dress up in Colonial garb and serve recipes from that period.
