Our regular hours are from 9:30 a.m. to 4 p.m. Extended hours are offered during spring break, summer, and winter holidays—check our full calendar of extended hours. We are open every day except Thanksgiving and Christmas. 

Full payment is due 14 days before your visit or your reservation will be canceled. Cancellations made less than 14 days in advance will not be refunded. Please provide your final group count 14 days before your visit; students or chaperones not included in the final count will be charged full-price admission.

Breakfast may be the most important meal of the day, but lunch plans make the most of your day at Griffin MSI. With so much to do and see at Griffin MSI, the last thing your group will want to do is spend time on lunch logistics. Make that plan in advance!

We will ask for your lunch plan during your reservation process. When bringing your own lunches, a time and space for your lunch must be prearranged. These lunch options are available:

Group Lunch Vouchers (pre-paid vouchers, open seating)
Museum Vouchers ($22 per person) are good for one entrée, one side, and one canned water or fountain soda in the Museum Kitchen. Seating is open and is subject to availability. Select this lunch option during your reservation request.

Bringing Your Lunch (requires seating reservation)
Bringing lunches still requires scheduling a time and space to eat. Seating is limited and available on a first-come, first-served basis, so be sure to choose the "Bringing our own" lunch option during reservation.

Convenient motorcoach access is available for drop-off and pick-up of your group. Your reservation materials will confirm your assigned location and provide directions. You will be directed either to our Group Center entrance on the Museum's west side or to the main entrance drive on the building's north side.

While not available at Griffin MSI, motorcoach parking is available at the McCormick Place truck marshalling yard, located at 31st Street and DuSable Lake Shore Drive. For more information on motorcoach parking and loading zones in the City of Chicago, please visit Choose Chicago.

Paid automobile parking is available in the Museum's underground garage. Oversize and van-accessible parking spaces are all located in the garage's Blue (D) section, where height clearance varies from 8'2" to 7'2" (check signs). There are also accessible parking spaces in all other garage sections, where height clearance is 6'6". Entry from the garage to the Museum is wheelchair accessible.
