Please note the following exclusions to the ASTC Travel Passport Program:*

  • The ASTC Travel Passport Program only entitles visitors to free general admission at participating science centers/museums. It does not include free admission to special exhibits, the COSI Motion Simulator, museum stores or parking.
  • To receive Travel Passport Program benefits, you must live more than 90-miles away from the center/museum you wish to visit. The admission staff has the right to request proof of residence to apply the benefits. Per ASTC policy, this distance is measured “as the crow flies,” meaning that it is based on the linear radius between your place of residency and participating science center/museum you plan to visit, not driving distance.
  • Additionally, Science Centers/Museums located within 90-miles of each other are excluded from the Travel Passport Program unless exclusion is lifted by a mutual agreement. 90-miles is measured "as the crow flies" rather than by driving distance. COSI Members visiting the Boonshoft Museum of Discovery (Dayton, Ohio), the Works (Newark, Ohio), and the SPI-Spot (Mt. Vernon, Ohio), will receive 50% off general admission due to separate reciprocal agreements.
