$13 ($26 value) for admission for two to Sea Lion Aquatic Park in Lisle. Limit four per person, additional two as gifts. This is a great water park – it’s conveniently located, with lots of separate areas/pools for all age groups, from the zero depth baby splash pools to waterfalls and slides for the thrill-seeking teenagers. And about three lifeguards for every kid (well, it seems like that, anyway). We didn’t get passes this year ’cause we were kinda stuck doing other water-related chores, so I’ll probably grab this one – it’s cheaper than my resident rate.
