We'd like to know which historical sites to visit during our mid-June 2.5 day visit with our 9-year-old son. Specifically-what sites give the most information? Do you get alot of the same info at several sites. Are certain sites busier on certain days or at specific times of the day? Is there a good route of certain sites to visit? In any specific order? Are there any sites not really worth paying to go into? We'd appreciate ANY advice anyone can offer. Thanks!
P.S. Are there any fun site (like Waterparks) to visit close-by?
