Our staff will always use the address on your photo ID to make this determination. If your museum membership includes reciprocity with the Association of Children's Museums, indicated by a red circle on your membership card, then you would qualify for 50% off general admission for up to 6 total people on your membership. For more information about your membership's reciprocity, we recommend calling your home museum. *If you are a member of Boonshoft, Spi Spot, or The Works you qualify for 50% off admission regardless of the distance you live from COSI.
