"The world-renowned San Diego Zoo spans 100 acres and houses more than 12,000 rare and endangered animals. Plan to spend at least a half-day at the zoo to get the full experience, which includes shows and animal presentations. During the summer, Nighttime Zoo event series allows visitors to stay later into the evening. There are plenty of restaurants throughout the park where parents can recuperate with a much-needed afternoon beer." - Marie Tutko, Archana Ram
