Courtesy photo/Hurricane Harbor Chicago Thrill-seekers can finally feel that adrenaline rush they’ve been waiting for this summer as water parks begin reopening across Illinois. Six Flags Great America’s Hurricane Harbor locations in Gurnee and Rockford and Santa’s Village water park Santa Springs will reopen Saturday. “Memorial Weekend is always the unofficial start of summer here at Six Flags, and we’re so excited to have some splash and some fun,” said Caitlin Kepple, Six Flags’ communications and marketing manager. This marks the first time Hurricane Harbor Chicago in Gurnee will operate separately from the Six Flags theme park next door — making it the company’s 27th park, with three in Illinois.
