We recommend giving yourself extra time to park (free days are usually crowded), bring $5 per person to ride the fun wildlife carousel, bring your stroller or wagon for the young'uns who might tire out easily (and for a place to store your sack lunches), and pack plenty of food, snacks, and drinks (but no glass bottles, plastic straws, or alcoholic beverages).
