At Six Flags Great America, the park generally remains open during rain, but safety protocols dictate that most high-profile outdoor rides and roller coasters will close if the tracks become too slippery or if there is any lightning within a certain radius (usually 10 to 15 miles). While some smaller attractions and indoor shows may continue to operate, a heavy downpour often leads to a "temporary suspension" of major thrills like Raging Bull or Maxx Force. If the weather remains severe and the park is forced to close early, Six Flags typically offers a "Rain Check" policy. If you have been in the park for less than a certain amount of time (often 4 hours) and the majority of rides are closed for an extended period, you can go to Guest Relations to receive a ticket for a return visit later in the season. It is important to note that no cash refunds are given. Many savvy visitors use rainy periods to shop in the covered stores on Main Street or eat at indoor dining locations, waiting for the storm to pass, as crowds often thin out significantly after a rain shower.
