OK - So we've ditched the plan to brave the mountains in an RV in October and instead thinking we'll fly into Miami, then drive to Orlando and from there make our way West as far as Dallas. Is it worth going via Jacksonville? We would have around 10-12 days and definitely want to go to New Orleans, was originally thinking of adding Nashville but now maybe will head along the Gulf Coast and then up to Shreveport. From Dallas I though we would fly to Phoenix, and drive to LA via Flagstaff, the Grand Canyon NP and Vegas (about one week.) We would be using hotel/motel accommodation.
