The ASTC Travel Passport Program entitles visitors to free general admission to participating science centers/museums. It does not include free admission to special exhibits, larger-screen theater presentations nor does it include museum store discounts or benefits. Program Restriction: Admission eligibility is based on your science center/museum's location: 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. Admission eligibility is based on Member's Residence: 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. 90-miles is measured "as the crow flies", not by driving distance.
