Disneyland trip! If Disneyland is the major reason for your trip and you only have 10 to 12 days available for your trip, I would suggest you consider flying into L.A., renting a car and staying at the Disneyland Hotel. 6 out of your 12 days will be spent bouncing down the highway. Your proposed 400 miles per day trip is more like a marathon and guaranteed to give you a case of SORE A_ _! with little time to stop, rest and enjoy the trip!! Driving a RV in southern Calif. is a nightmare for me. I will drive 100 miles out of my way to avoid driving anywhere near L.A. And yes I use to live in L.A.
