Reserve your admission entry time. A team member will validate your veteran ID at the Accessible sales desk before you enter. Free admission is for veterans only, but you can purchase tickets for your family and friends. After completing your reservation, click "Get Tickets" at the top of the screen to reserve tickets for additional guests. If there are more than two veterans in your party, please call us at 312-939-2438 to reserve. Due to high call volume, we recommend calling at least 24 hours in advance.
