Thanks, everyone, for the information. My kids were so entranced by their first experience at the parks that they didn't even end up asking to buy a toy. (But I did give multiple speeches about how this trip was about enjoying family time and rides, not about buying things or spending time in stores...)
I am surprised that they don't sell any Cars stuff near the Lightning McQueen's Racing Academy. My kids probably would have been interested if they saw that merchandise after the show!
