Thats a great idea. My home park is Canada's Wonderland and any one I talk has no idea that its owned by Cedar Fair. I have always said they do a poor job advertising the Platinum passes. Wonderland only advertises a regular season pass.
As far as people saying the cost for a season pass is too much, it is if you pay all at once. Now that they offer a 12 month payment plan they have made it so almost anyone can afford it. For a platinum pass its only $15 a month. Thats cheap and something Cedar Fair should advertise more. I am sure if more people knew Cedar Point is included with a platinum pass they would buy it.
