Just curious....do you really want to experience the train? I think it sounds like a fun idea, but I hope your reasoning is not that it will save you money.
Well, it's not necessarily to save money, but I did think renting in just San Diego would be cheaper than renting in Anaheim and returning to San Diego. I was also thinking that I always hear the traffic in LA is horrible and thought it would be a less stressful trip for everyone.
