My family and I want to visit family in Virigina this coming summer. We have NEVER traveled cross country before. We are hoping to be traveling in an RV, but if things don't work out we will be towing a travel trailer beind our family vehicle. Since the children range in age from 12 to 4, we need fun/educational stops on the way. Can anyone recommend a quick, but fun route? Also, any cost saving tips would be greatly appreciated.
