And there's Beech Bend in Bowling Green KY with a 2006 GCI woodie and then there's Hard Rock Park opening in 2008 in Myrtle Beach SC (although a bit out of the way). I see Six Flags Over Georgia is along the way... Lake Winnepesaukah (Lake Winnie) isn't too far off course and could be combined with a stayover trip to Dollywood. The kids would probably love Cypress Gardens in FL and it would be good training grounds for junior coaster enthusiasts although this would be a destination while in Orlando...
My suggestions from here would be to use the tree view (advanced search option) on rcdb.com to find out what parks exist in the states you will pass through/by then look to see what they offer... Unfortunately this gives you the defunct parks as well. *** Edited 4/26/2007 4:44:20 PM UTC by jshorerzd***
