Sea Lion Aquatic Park in Lisle promotion is still available – two tickets for $13.  They completely remodeled this place a few years ago and did an excellent job of catering to all ages.  There is a zero gravity pool, toddler splash section, a teenagers only pool with waterfall and tubes to shoot down (two are high and two come out at water level).

Two-hour electric boat rental for eight to ten people ($99) or two-hour jet ski rental ($175) from the Vantage Yacht Club on the Chicago River.  Looks like a great family outing idea, doesn’t it?  Actually, either one of these deals would work for everyone in the family.  Well, not teenagers, but then they don’t work, so why should these deals…
