Management could charge double for high traffic rides.
Cedar Point in Sandusky, Ohio has general admission and the newest ride always has long lines.
They have front of the line special admission prices but that only get's you so far.
Personally I think that charging double for certain rides would be fairer and cause fewer issues with customers.
"Management" is a family and their trusted staff at Knoebels. What they do at Cedar Point is up to their corporate overlords and has no bearing or influence on Knoebels.
