Went to Fly over Canada and parked my vehicle at the underground parking. Upon my exit the ticket paying wasn't functioning properly as it did not cash or credit cards and so we had to go the cashier. They should have a better system or better equipment as we paid $12 for about 1 hr of parking. Very disappointed. This us the 2nd time this had happened.
