The thing I found funny with their pass processing was the difference in height requirement between the Cedar Point pass and the Platinum Pass. For the Cedar Point pass, a junior pass is measured as a kid 48" or less when measured with their shoes ON. A Junior Platinum Pass is defined as 48" or less when measured in bare feet! Seems a little strange to me!

That is due to that fact a PP gets you into Soak City and other water parks in which height is measured shoeless. As for just CP all ride measurements require shows, although SRF and TC shoes are not required to ride.
