We will be coming to LA in June, we are staying in Santa Monica. We want to do a lot in 2 days. Peterson musuem, walk of fame, chinese theater, farmers market. We will have a rental car, but I don't know if it would be better to take a tour or try it on our own. Is it fairly easy to drive? Need help. Don't want to spend 2 days getting lost and trying to find our way around.
