We're taking our kids to California for spring break and are very excited about seeing the San Diego Zoo and Safari Park. The problem is, we only have one day for each. We're regulars at the Bronx Zoo and have been to Zoo Miami several times, so we're willing to skip animals that are at those zoos if we have to. I'd love your advice on what to see first, what order to view the different areas, etc. We're very used to walking, and we walk quickly. How much of the Zoo can we see in one day if we arrive when it opens and leave at closing? Also, is it worth doing the "Panda Trek" now that the pandas are gone? Thanks!
