Way back in 1976 when Marriot opened Great America, it revolutionized the theme park industry. It was one of the first theme parks to let you ride the attractions WITHOUT having coupons or tickets for each individual one. The entry fee was all that you would pay. And the entertainment that Marriot brought in back then was top notch. I remember seeing Sonny and Cher and even The Who. The park was built with the intention of lengthening the stay of guests at the brand new 5-star Marriot Lincolnshire Resort and Golf Course, and for the first few years, such things as Early Entry and Late Night Stays were tacked on to Marriot guests visits. The food was all prepared by Sous Chefs and again reflected Marriot's goals of being the best. The Skyway, SkyWhirl and there was a third cable attraction which didn't last more than a year. Six Flags bought Great America from Marriot when Marriot could no longer afford to run the operation to its high service level at a profit. It's a shame what SF did to GA, but now it is one of the coaster kingdoms of the world, second only to Cedar Point. There are 8 roller coasters at SFGA, and 3 of them are actually nationally known and 2 of them are even Woodies.
