Platinum Pass Redeeming Question

Ok. So I recently bought the Kings Island Platinum Pass thinking that I would be going there before Cedar Point, this did not happen and now I am wondering. Since the Platinum Pass is valid for all Cedar Fair parks, does the voucher that I have need to be redeemed at Kings Island, or can this be done at Cedar Point?

It can be done at Cedar Point. Last year we bought our Platinum Pass through Cedar Point and redeemed it at Kings Dominion.
