Welcome to the Six Flags Reservation System! To meet social distancing guidelines and ensure the health and safety of our guests, all visits to the park must be pre-scheduled. This allows us to control the flow of people at the front gate at any given time.

Making a reservation is quick and easy! You will need to have your online order number, ticket number, or Membership/Season Pass number handy. 

Reserve Your Visit to Holiday in the Park Lights

Rides and some attractions at Six Flags Great America remain temporarily closed. Following local and regional COVID-19 health directives, we will open those soon as it is safe to do so. Capacity to Holiday in the Park Lights is limited by day, and all guests must make reservations ahead of time.

Members & Season Pass Holders may begin making reservations now.

Reservations for Ticket Holders opens at 12 pm on October 15.
