We are heading to Chicago next week and plan to spend 2 days at Six Flags. 2 adults and 3 kids (3,7,9 years old). We were thinking of buying a season pass for each of us, as it looks like that will be less expensive than buying 2 single day tickets for each person. Does anyone know if there are coupons available in the Chicago area, like on grocery items/cans of pop or anything? Any other discounts available? Thanks!
