Hello everyone:
My family and I live in Argentina, South America. We are planning a trip to New York, Philadelphia and DC in July 09. After completing that tour I would like to drive from Washington DC to Memphis going through Kentucky (Louisville and Lexington) and take the famous Blueridge Parkway and back to DC for my flight back home.

I need recomendations as to which route to do going out from Washington, as well as getting back not going through the same places. Also : is the Blueridge Parkway worth it it´s whole extension? Is it better taking it North to South or the other way ?

Since I´ll be traveling with two kids ( 8 and 11 years old) I need to know if there are any amusement parks or similar attractions in the route I mentioned at the beginning , just in case they get tired of so much scenic drives.
