San Diego Zoo is rated the best because IT IS! the animals were out and alert, parking is free, yes you can bring a personal cooler and pack your snacks, water, etc. With any large attraction park it was crowded when we arrived, but we purchase our tickets online and was able to walk in with waiting in line. Leaving wasn't a problem, no crowed, and the expressway is nearby
