Irvine has some of the best themed parks, and this one was a favorite when my kids were younger. (And of course, coming to a park with kids, you make sure to bring sunscreen, water, and baby wipes to take care of their "boogers"). We came out today to join a friend and her young daughter. There aren't many places here to hide a cache, but we found one good spot for our first hide of this type.
This should be a quick P&G for the numbers. However, feel free to take some extra time to enjoy the park, the walking trail around the field, and the exercise equipment.
Use stealth and BYOP. Room for very small give & take swag.
