We are travelling to San Diego in October. After spending a week in Anaheim we are going to rent a car and drive down. We are looking at the La Jolla area just because my husband has been there on business before. He never really got a good chance to explore though. We would like to be within 20-30 minutes driving of Sea World and close to a decent beach area. We are travelling with our two daughters, ages 6 and 9. Any suggestions/thoughts?
