Retail therapy, anyone? Hit the King of Prussia Mall, the country’s second-largest shopping center, which draws more than 20 million visitors annually. The retail hub — with its 450 stores — is just a few blocks from the hotel, so shoppers need not worry about lugging their purchases far on foot. After exercising their credit cards, Revolutionary War buffs and nature lovers alike should head to Valley Forge National Park to see the site of the Continental Army’s 1777-78 winter encampment and General George Washington’s headquarters. Hikers can take on more than 30 miles of trails with impressive views of Valley Forge’s historical monuments. College football fans, meanwhile, can catch a Villanova Wildcats game at the university’s stadium.
