Admission Updates All admission tickets require a reservation. This includes all tickets for members or other free ticket options. If you have any issues reserving your tickets please call Visitor Services at (405) 325-7977 to reserve your tickets over the phone. There are a limited number of tickets available for each of the four daily time-slots, so make sure to book ahead! Due to COVID-19 restrictions and our Health and Safety Guidelines, we are limiting groups to 10 people or fewer at a time. There is a time limit of one and a half (1.5) hours in the museum to help maintain healthy social-distancing. Please arrive as close to your scheduled time-slot as possible to ensure the most time for your visit. If you are booking a free ticket (i.e. for members or veterans), please show valid I.D. at the Visitor Services desk when you arrive. Please contact Visitor Services at (405) 325-7977 for help with any questions or concerns regarding our new Health and Safety Guidelines.
