^Well, yea the decision was made mostly with less spending in mind.
And of course one side will not open on slow days or in the early morning ect.
but I can assume that on days when each train is filled, Cedar Fair will try to RACE them. Gemini, for example, always racing when both sides are open.
I mean think about it:
What kind of an example do you want to set for the guests, (by guests I mean people who don't know The Racer), having The Racer not RACE?
