My partner and I are thinking of attempting to drive from LA to Orlando on the I10 sometime next year. We have no experience driving in the US, here at home a 4 hour drive is considered a marathon. Can anyone advise on time of year, best rental car options, type of car, GPS or not, stopovers, etc. We were thinking of stops at Tucson, El Paso, Houston and Mobile or Fort Walton. These look good on Google Earth but you can't beat local knowledge. Any advice would be very much appreciated.
