As everyone has said, it's pretty easy, especially if you have a navigator, allowing you to concentrate on getting used to the car and the fact you're on the wrong side of the road. I won a trip to LA back in '93, with a hire car. Took a mate with me and having him there with a Rand-Macnally map was a huge advantage. First problem was figuring out how to unlock the filler hatch on the Buick Skylark I was given, second was working out how to get out of the area without driving into South Central in an obvious hire car. Generally I got used to the auto and driving on the right pretty quickly, but I did get caught out turning right at a junction that went under a freeway overpass, possibly Ventura, and found myself on the wrong side of the road with a car coming towards me! Eek. Had a great time, it was terrific fun driving to Santa Monica and Venice, drinking cold Guinness while sat looking at the Pacific Ocean. Have fun, enjoy the experience, I'm really jealous.
