Hi, Hope you can help please. My husband and I are travelling from LA to San Diego on the train and I wasn't planning on hiring a car but now I am reconsidering. We will be staying 4 nights and hope to visit Sea World, perhaps the zoo, La Jolla and Midway. Also need to get to the airport to depart San Diego. In addition, my husband has announced that he needs to buy walking shoes/runners in San Diego before we do anything. I believe to get to the outlet stores you need a car - is there a huge difference in prices between the outlet and normal shopping stores to make hiring a car worthwhile? I don't want to spend a long time shopping. Looking at approximately $30 per day car hire. Any advice gratefully appreciated.
