When we did that drive last year from Syracuse we stopped at Hershey Chocolate world on the way down. It's probably a bit out of the way for you, , but our kids thought is was a fun time. The ride is free, and otherwise it's really a big food court/souvenir stand for Hershey, but worth the time if you're going by anyway, takes about a hour to two hours, less if you don't like to shop at all.
